[0001] This application claims priority to U.S. Provisional Patent Application No. 63 / 535,718, filed August 31, 2024, and entitled “Vial Adapter, System and Method,” the entirety of which is incorporated herein by reference. TECHNICAL FIELD
[0002] The present invention relates generally to liquid chromatography systems. More specifically, the present invention relates to liquid chromatography sample managers and associated systems and methods. BACKGROUND
[0003] Chromatography is a group of techniques for separating mixtures into their components. For example, in a liquid chromatography system, a pump draws in a mixture of liquid solvents and delivers it to a sample manager, where an injected sample awaits its arrival. In isocratic chromatography systems, the composition of the liquid solvents remains constant, while in gradient chromatography systems, the solvent composition varies over time. A mobile phase consisting of a sample dissolved in the solvent mixture passes through a column, known as a stationary phase. By passing the mixture through the column, the various components in the sample separate from one another at different rates and thus elute from the column at different times. A detector receives the elution from the column and produces an output from which the identity and quantity of the analytes can be determined.
[0004] Before a sample is provided into a liquid chromatography system, it can be provided to a sample manager. The sample manager can be configured to prevent the sample from degrading or becoming compromised while it is provided into the liquid chromatography system. The sample manager typically interacts with a technician, and therefore must be user-friendly, reliable, accurate, robust, durable, and cost-effective.
[0005] Some sample managers can receive a number of sample vials that can be disposed within a sample vial tray or rack. Other sample managers require a technician to input individual vials. Such single-input sample managers can deploy, for example, a carousel system, whereby the technician is provided access to a single location on the carousel to insert a new single vial. Due to the complexity of the carousel and needle system within the sample manager, such sample managers are typically able to accept vials of a single size and / or dimensional arrangement. SUMMARY

[0040] Reference to“one embodiment” or“an embodiment” within this specification
[0041] The present teachings will now be described in greater detail in connection with the exemplary embodiments of the present teachings as illustrated in the following drawings. While the present teachings are described in conjunction with various embodiments and examples, it should be understood that the present teachings are not limited to such embodiments. Rather, the present teachings cover various alternatives, modifications and equivalents, as would be appreciated by one of ordinary skill in the art. Additional embodiments, modifications, and embodiments within the scope of the present teachings as described herein will be recognized by those of ordinary skill in the art. It will be recognized that additional embodiments, modifications, and embodiments within the scope of the present teachings will become apparent and / or recognized from consideration of the specification and / or drawings and / or practice of the teachings as set forth herein.
[0042] As described herein, prior to conducting a liquid chromatography run, a technician loads a vial containing a sample into a sample manager vessel or receptacle of individual sample vials. The sample manager system includes a sample delivery system configured to transfer the sample from the sample vial holder to the chromatography flow stream. The heat treatment chamber includes a sampling mechanism including a rotating sample vial turntable in order to process a sample that has been provided to the vessel or receptacle. At least one sampling needle that is part of the sampling mechanism is located within and / or accessible to the heat treatment chamber that can draw a sample from the vial and inject the sample into the chromatography flow stream. As contemplated herein, the sample manager and sample delivery system along with its turntable can be particularly configured for sample vials having acceptable, preferred, and / or specifically defined dimensions. Due to the engineering complexity of the turntable, sensor, and needle design, such a system can not be configured for sample vials having dimensions different than the acceptable, preferred, and / or specifically defined dimensions. However, it can be desirable to process sample vials having dimensions different than the acceptable, preferred, and / or specifically defined dimensions by such a configured sample manager. In such instances, the present embodiments contemplate changing the dimensions of different sample vials with a sample vial adapter in order to be able to be processed by the sample manager that would not otherwise be configured to process the different sample vial due to the different dimensions. While the embodiments described herein can be particularly applicable to single load sample vial systems having a turntable system, the application of a sample vial adapter as described herein can be applicable to any system where it is desirable to change the dimensions of a sample vial for the purpose of facilitating the automated system's interaction with the sample vial.
[0043] The features of the sample delivery system and sample manager heat treatment chamber described herein can be applicable to any liquid chromatography system configured to deliver a sample to a chromatography flow stream. As one example, Figure 1 An embodiment of a liquid chromatography system 10 for separating a mixture into its components is shown. The liquid chromatography system 10 includes a solvent delivery system 12 in fluid communication with a sample manager 14 (also referred to as a sampler or autosampler) through tubing 16. The sample manager 14 is in fluid communication with a chromatography column 18. A detector 21, such as a mass spectrometer, is in fluid communication with the column 18 to receive elutions.
[0044] The solvent delivery system 12 includes a pumping system 20 in fluid communication with a solvent reservoir 22 from which the pumping system 20 draws solvent (liquid) through tubing 24. In one embodiment, the pumping system 20 is embodied by a hybrid system having one or more pumps. The liquid chromatography system 10 can be, for example, an ultra performance liquid chromatography (UPLC) system, although the present application is not limited to this embodiment. For example, in a low pressure gradient pumping system, mixing of solvents occurs prior to the pump, and the solvent delivery system 12 has a mixer 26 in fluid communication with the solvent reservoir 22 to receive various solvents in metered proportions. This mixing of the solvent (mobile phase) composition is varied over time (i.e., varies in a gradient). However, in other embodiments, mixing can occur after the pumping system 20 but before providing the chromatographic stream to the sample manager 14.
[0045] The pumping system 20 is shown in fluid communication with the mixer 26 to draw a continuous gradient stream therefrom for delivery to the sample manager 14. Examples of solvent delivery systems that can be used to implement the solvent delivery system 12 include, but are not limited to, the ACQUITY Binary Solvent Manager and the ACQUITY Quaternary Solvent Manager manufactured by Waters Corp., Milford, Mass.
[0046] The sample manager 14 can include an injector valve 28 having a sample loop 30. The sample manager 14 can operate in at least two states: a load state and an injection state. In the load state, the position of the injector valve 28 is such that the sample manager loads a sample 32 into the sample loop 30. The sample 32 is drawn from a vial contained in a sample vial holder. A "sample vial holder" herein refers to any device configured to hold a sample vial, such as a well plate, a sample vial holder, etc. In the injection state, the position of the injector valve 28 is changed such that the sample manager 14 introduces the sample in the sample loop 30 from the solvent delivery system into the continuous flow mobile phase. Thus, the mobile phase carries the sample into the column 18. In other embodiments, a flow through needle (FTN) can be utilized instead of a fixed loop sample manager. Using the FTN method, a sample can be pulled into a needle, and then the needle can be moved into a septum. A valve can then be switched to put the needle in line with the solvent delivery system.
[0047] The liquid chromatography system 10 also includes a data system 34 in signal communication with the solvent delivery system 12 and the sample manager 14. The data system 34 has a processor 36 and a switch 38 (e.g., an Ethernet switch) for handling signal communication between the solvent delivery system 12 and the sample manager 14. Signal communication between the various systems and instruments can be electrical or optical, using wireless or wired transmission. A host computing system 40 is in communication with the data system 34 through which a technician can download various parameters and configuration files (e.g., an inlet gas velocity configuration file) to the data system 34.
[0048] Figure 2 A perspective view of the liquid chromatography system 10 is shown, including the sample manager 14, the detector 21, the chromatography column 18, the solvent delivery system 12, and the pump system 20, as well as the solvent 22. Each of the sample manager 14, the detector 21, the chromatography column 18, the solvent delivery system 12 can include a housing or body within which various features can be housed. Further, the entire liquid chromatography system 10 is connected to a data system 34 (e.g., a computer system) that includes a user interface and / or display device 41. The various components 12, 14, 18, 19, 21, 22 of the liquid chromatography system 10 can be interconnected with fluidic tubing and in signal communication with the data system 34 of the system and / or the host computing system 40. The liquid chromatography system 10 is shown with the solvent delivery system 12, the sample manager 14, the chromatography column 18, the detector 21, and a plurality of trays for holding solvent 22, as well as a waste container 42. The liquid chromatography system 10 can be, for example, a PATROL UPLC system manufactured by Waters Corp., Milford, Mass.
[0049] Figure 3 A sample vial 100 is depicted in accordance with one embodiment. The sample vial 100 includes a body 110 extending between a top end 112 and a bottom end 114. Near the top end 114, the sample vial 100 also includes a top cap 116. The top cap 116 can be threadedly engaged or crimped to the body 110 of the sample vial 100. In other embodiments, the top cap 116 can be attached to the body 110, for example, by a press fit or an interference fit. The top cap 116 can include a top structure 115 that can be configured to hold a sample within the sample vial 100, but can also be thin enough to be pierced by a sample needle (not shown) from the sample manager 14.
[0050] The body 110 of the sample bottle 100 can be generally cylindrical in shape. The top end 114 of the generally cylindrical body 110 can include a narrowed or tapered portion 117. A neck 118 extends from the narrowed or tapered portion 117. The neck 118 can include external threading for receiving internal threading of the top cap 116 in a threaded arrangement.
[0051] The dimensions of the sample bottle 100 shown are exemplary, and the principles of the embodiments described herein can be applicable to any sample bottle structure having a generally cylindrical or cylindrical body. In other embodiments, various dimensions of the sample bottle can be different, such as the height of the sample bottle, the circumference of the body, the shape of the top end 112 (i.e., the shape or taper of the narrowed portion 117 and the dimensions of the neck 118), the height or circumference of the top cap 116, etc. In some embodiments, the sample bottle can not include a tapered portion or neck, and can simply include a cylindrical body extending to a threaded end for receiving a top cap. Regardless of the embodiment, the present disclosure contemplates shaping the sample bottle adapter to match and / or correspond to the dimensions of the sample bottle 100, as described below.
[0052] Figure 4 A perspective view of a sample bottle adapter 200 according to one embodiment is depicted. The sample bottle adapter 200 includes a body structure 210 extending between a top end 212 and a bottom end 214. The body structure 210 defines a channel 216 for receiving a sample bottle 100. While a particular channel dimension of the channel 216 has been shown to fit the dimensions of the sample bottle 100, other channel dimensions can be contemplated in order to accommodate sample bottles of different sizes and dimensions.
[0053] In any case, the channel 216 can be sized to at least partially encircle the received sample bottle 100. The channel 216 can extend a majority of the length of the body structure 210 from the top end 212 to the bottom end 214. The channel 216 can wrap about 180 degrees around the sample bottle 100. In some embodiments, the channel 216 can wrap greater than or less than 180 degrees around the sample bottle 100.
[0054] The body structure 210 includes a channel opening 218 configured to receive the sample bottle 100 within the channel 216. The body structure 210 also includes a plurality of extensions 220a, 220b, 220c, 220d that reduce the width of the channel opening 218. The extensions 220a, 220b, 220c, 220d are shown to include curved extending edges 222 that extend the extensions 220a, 220b, 220c, 200d into the channel opening 218. The extensions 220a, 220b, 220c, 220d maintain the curvature of the circumference of the channel 216 and the body structure 210 and extend to a flat axially extending edge 224. In other embodiments, the extensions 220a, 220b, 220c, 220d can be slightly curved inwardly such that the received bottle will be held in the channel 216 by a constant biasing force provided by the extensions 220a, 220b, 220c, 220d.
[0055] Regardless of the embodiment, the first extension 220a and the second extension 220b can form a first pair of extensions located at a first axial position of the body structure 210, while the third extension 220c and the fourth extension 220d can form a second pair of extensions located at a second axial position of the body structure that is lower than the first axial position. Any number of pairs of extensions can be envisioned. For example, the body structure 210 can include a single pair of extensions, or can include more than two pairs of extensions. In some cases, the body structure 210 can not use pairs of extensions, but can include a single flexible extension that extends from only a single side of the channel opening 218.
[0056] The extensions 220a, 220b, 220c, 220d and / or the body structure 210 can each be configured to elastically deform and / or deflect during the process of receiving the sample bottle 100. This process is shown more clearly in Figures 5 to 6 The extensions 220a, 220b, 220c, 220d and / or the body structure 210 can be configured to return to the original position (i.e., as shown in Figure 4 FIG. 1) upon receiving the sample bottle 100 and to hold the received sample bottle 100 within the channel 216. To achieve this deflection or elastic deformation, the body structure of the sample bottle adapter 200 can be made of, for example, a plastic material, a polymer, a composite material, or even a flexible metal material. Regardless of the material, the flexibility should be such that the extensions 220a, 220b, 220c, 220d can flex when receiving the sample bottle 100 and allow the sample bottle 100 to snap into place within the channel 216 via, for example, a snap fit, after which the sample bottle 100 is securely held in the channel 216 until intentionally removed. Removal can require the extensions to flex or elastically deform again in order to allow the sample bottle 100 to be removed.
[0057] In some embodiments, it is contemplated that a sample vial received in the channel 216 via a snap fit can be held against a small degree of outward flexing force on the protrusions 220a, 220b, 220c, 220d. For example, when the sample vial 100 is received in the channel 216, the circumference or size of the sample vial 100 can be large enough to extend into the space occupied by the original position of the protrusions 220a, 220b, 220c, 220d.
[0058] The top end 212 of the body structure 210 includes a mock cap structure 230. The mock cap structure 230 can be designed in a size similar to an actual cap. However, the mock cap structure 230 can instead be an integral feature of the body structure 210 and can not be removable from the body structure 210. The mock cap structure 230 includes a top surface 232 having an opening 234. The opening 234 can be configured to provide access for a sample needle or syringe needle into a received sample vial 100.
[0059] The body structure 210 also includes a back opening 240 at the bottom of the channel 216. The back opening 240 can be configured to provide access for a technician’s finger to press a received sample vial 100 through the body structure 210 to facilitate removal of the sample vial 210 from the channel 216 and the body structure 210. While a single opening is contemplated as shown in the figures, in other embodiments, more than one back opening can be included. For example, the body structure 210 can include a second back opening configured to provide access for a second finger of a technician to press a received sample vial 100 through the body structure 210 to facilitate removal of the sample vial 100 from the channel 216 and the body structure 210.
[0060] The body structure 210 forms a substantially cylindrical shape with the removed channel opening 216. This shape can be configured to mimic, represent, or replicate an acceptable, preferred, and / or standard shape of a sample vial configured for a particular sample management system. The acceptable, preferred, and / or standard shape of a sample vial can be a shape that is specifically designed to be acceptable to a sample vial holder system, needle design, and sensor system of a sample manager that has been specifically configured to be optimized for that acceptable or preferred shape and size. While the contemplated embodiment shows one example of an acceptable or preferred shape, the body structure 210 can take other shapes depending on the design of the corresponding sample manager system.
[0061] Figure 5 A sample vial 100 partially received in a channel 216 of a body structure 210 is depicted in accordance with one embodiment Figure 3 Figure 4 A perspective view of a sample vial adapter 200. As shown, the bottom of a sample vial 100 is shown first inserted into the sample vial adapter 200. Once this occurs, the top of the sample vial 100 can be pressed into the sample vial adapter 200, deflecting the body structure 210 and / or the protrusions 220a, 220b, 220c, 220d of the sample vial adapter 200 in order to snap the sample vial 100 into place within the channel 216. Figure 6 A perspective view of a sample vial adapter 200 according to one embodiment is depicted. Figure 4 A perspective view of a sample vial adapter 200 according to one embodiment is depicted. Figure 3 A perspective view of a sample vial adapter 200 according to one embodiment is depicted.
[0062] Figure 7 A method 700 of adapting a sample vial, such as sample vial 100, according to one embodiment is depicted. The method 700 can include a first step 710 of determining a circumference of a sample vial, such as sample vial 100. The sample vial 100 can be substantially cylindrical. The method 700 can include a second step 720 of determining a height of the sample vial.
[0063] The method 700 can then include a step 730 of determining acceptable dimensions of a sample vial for a given sample manager. These dimensions can be well known and can represent dimensions of a standard sample vial that is configured for use with a given automated sample manager and can also be configured to be individually received and processed by the sample manager. The acceptable sample vial can also be substantially cylindrical in shape and can have a circumference and a height that are greater than the circumference and height of the sample vial of steps 710, 720.
[0064] The method 700 then includes a step of forming a sample vial adapter, such as sample vial adapter 200.
