Description

Technical Field

[0001] This utility model relates to the field of mass spectrometry detection technology, specifically to a quick-detachable waste gas condensate membrane desolvation device. Background Technology

[0002] Membrane desolvation is a sample pretreatment technique used in inductively coupled plasma mass spectrometry (ICP-MS) analysis. It utilizes the selective permeability of a semi-permeable membrane to allow solvents to permeate and be removed. Membrane desolvation reduces matrix interference from analytes and improves elemental sensitivity. In existing technologies, membrane desolvation devices typically consist of a nebulizer-heating module and a desolvation module. The desolvation module can be directly composed of a membrane desolvation module or a two-stage desolvation module (Peltier condensation desolvation + membrane desolvation). The membrane desolvation device, consisting of a nebulizer-heating module and a membrane desolvation module, operates as follows: In the nebulizer-heating module, a concentric nebulizer sprays the sample solution as an aerosol into the heated nebulization chamber. The sample is heated and maintained in the gas phase within the nebulization chamber, and then the sample vapor is introduced into the membrane desolvation module. In the membrane desolvation module, the sample vapor flows through the heated semi-permeable membrane. The solvent permeates through the semi-permeable membrane and is carried away by the countercurrent purge gas, leaving only the dry sample gas flowing out of the membrane desolvation module.

[0003] In membrane desolvation devices, the semipermeable membrane is a consumable item, and after prolonged use, it may become clogged or damaged, requiring timely cleaning or replacement. Most existing membrane desolvation devices are fixed, meaning the atomizing heating module and the desolvation module are permanently installed inside the device. To clean or replace the semipermeable membrane, the outer casing must be disassembled, the membrane desolvation module removed, and the inlet and outlet ports connecting to the semipermeable membrane disconnected before the membrane can be removed or replaced. This process is cumbersome, involves frequent disassembly and reassembly, requires limited operating space, and is highly susceptible to damage to other components, making membrane replacement a major drawback of such devices. For example, patent document CN223037537U discloses a drawer-type membrane desolvation device.

[0004] The new generation of membrane desolvation devices adopts an easily detachable structure. By separately encapsulating the membrane desolvation module, the module can be plugged in, removed, or spliced ​​onto the device, simplifying the replacement process of the semi-permeable membrane and reducing its difficulty. However, the new generation of membrane desolvation devices has not completely solved the pain points of the older generation. The complex structure and difficulty in disassembling the inlet and outlet interfaces connecting the semi-permeable membrane within the membrane desolvation module remain. Therefore, it is necessary to propose a quickly detachable waste gas condensation membrane desolvation device. Utility Model Content

[0007] Furthermore, the male connector includes an inner tube connector, an outer tube connector, and a male socket connected in sequence. The outer tube connector has a larger diameter than the inner tube connector on the side closest to the inner tube connector. The inner tube connector has an axial sample gas channel and is connected to the inner sleeve of the membrane desolvation tube. The outer tube connector has multiple sets of gas guide grooves symmetrically arranged on its outer surface and is connected to the outer sleeve of the membrane desolvation tube. The male socket is used to connect with the female socket of the female connector, and an annular purge gas chamber is formed between the male socket and the female socket.

[0008] Furthermore, the side wall of the sample outlet end of the female connector is provided with a sensitizing gas inlet and a purge gas inlet. The external interface of the sample outlet end of the female connector is plug-in shaped and has an O-ring groove. The external interface of the sample outlet end of the female connector is connected to the mass spectrometer's sample gas path. The sensitizing gas inlet is connected to the sensitizing gas inlet connector, and the purge gas inlet is connected to the purge gas inlet connector. The male connector is connected to the sample outlet end of the female connector to form the membrane desolvation interface sample outlet end.

[0009] Furthermore, a purge gas outlet is provided on the side wall of the female connector injection end, and the external interface of the female connector injection end is in the form of a socket; the external interface of the female connector injection end is connected to the heating atomization module, and the purge gas outlet is connected to the purge gas outlet connector; the male connector is connected to the female connector injection end to form the membrane desolvation interface injection end.

[0010] Furthermore, the inner sleeve and sample gas channel form an internal sample gas path; the outer sleeve, male connector gas guide groove, purge gas chamber, purge gas inlet, and purge gas outlet form an external purge gas path.

[0011] Furthermore, the condensing component includes a cooling fan, heat sink, cooling plate, condenser block and fixing plate arranged in sequence. The condenser block is installed in the main housing through the fixing plate, and the condenser block is provided with an exhaust gas passage that cooperates with the exhaust gas pipe.

[0012] Furthermore, a thermocouple is installed on the condenser block, and the thermocouple is electrically connected to a PID temperature controller.

[0013] Furthermore, the heating atomization module includes a concentric atomizer and a heating furnace.

[0014] Furthermore, it also includes a main housing and a membrane desolvation housing, with the heating atomization module disposed inside the main housing and the membrane desolvation module disposed inside the membrane desolvation housing, and a housing contact panel disposed on the membrane desolvation housing.

[0015] Furthermore, the main housing is L-shaped, the membrane desolvation housing is placed on the main housing, and the heating atomization module and the membrane desolvation module are fixedly connected by two fasteners.

[0016] The beneficial effects of this utility model are as follows:

[0017] The membrane desolvation module of this invention can be plugged in or spliced ​​on the device. When replacing the membrane desolvation, only the membrane desolvation module needs to be disassembled, making the replacement of the semipermeable membrane simple and easy to operate. At the same time, there is no need to disassemble other modules of the membrane desolvation device, effectively avoiding damage to other modules during the process.

[0018] This invention features a waste gas condensation function. By cooling the waste gas pipe, the stability of the membrane desolvation device can be improved. Applying the waste gas condensation function to the self-made membrane desolvation device increases the stability of the self-made membrane desolvation device by 0.74%.

[0019] Compared with existing easily detachable membrane desolvation devices, this invention has two advantages: First, it features a quickly detachable membrane desolvation interface. When replacing the semi-permeable membrane, the male connector of the semi-permeable membrane is connected to the female connector, which can be quickly plugged in and out. The semi-permeable membrane can be quickly removed by pulling out the male connector, optimizing the difficulty and operability of replacing the semi-permeable membrane. In contrast, traditional membrane desolvation interfaces require the semi-permeable membrane to be stretched completely through the interface and fixed with a small pagoda connector, a structure that is difficult to operate and prone to damaging the semi-permeable membrane. Second, the heating element is located inside the membrane desolvation module and closely attached to the membrane desolvation tube. This placement of the heating element inside the membrane desolvation module creates a semi-closed state, resulting in less heat loss. Furthermore, the close proximity of the heating element to the membrane desolvation tube provides more efficient heating. Existing easily detachable membrane desolvation devices have a semi-open membrane desolvation module, leading to lower heating efficiency and greater heat loss in the membrane desolvation tube.

[0020] This invention features a separately packaged membrane desolvation module, enabling rapid insertion, removal, and replacement. It also optimizes the internal interface structure of the membrane desolvation unit, allowing for quick disassembly and reassembly of the membrane desolvation tube and interface. Furthermore, the invention incorporates a waste gas condensation module, which cools the purge gas and solvent, thereby improving the stability of the membrane desolvation device.

When disassembling the membrane desolvation, the membrane desolvation housing 2 is first quickly inserted / removed by fastening / unfastening the fasteners 4, and then the reusable male connector 18 is pulled out from the membrane desolvation interface 9. Since both ends of the membrane desolvation tube 11 are connected to the male connector 18, the membrane desolvation tube 11 can be quickly disassembled through the male connector 18.

[0045] like Figure 5 and 6 As shown, the exhaust gas condensation module 14 includes an exhaust gas pipe 15, a condensation component 16, and a waste liquid collection tank.

Specifically, the cooling end of the cooling element 35 cools and conducts the low temperature to the exhaust pipe 15 through the condenser block 36, thereby cooling the purge gas in the exhaust pipe 15 and condensing the gaseous solvent in the exhaust pipe, thus improving the stability of the membrane desolvation device. The heating end of the cooling element 35 conducts heat through the heat sink 34 and dissipates heat through the cooling fan 33.

[0046] like Figure 4 and 7As shown, the membrane desolvation module 8 includes a membrane desolvation tube 11 and a heating element 13 closely attached to the membrane desolvation tube 11. The heating element 13 is a polyimide (PI) heating membrane.

Both the male connector 18 and the female connector 19 are provided with mutually cooperating sample gas channels 20. The female connector 19 is provided with a purge gas port. One end of the sample gas channel 20 is provided with an external interface 26, and the other end is provided with a female connector socket 25, which is connected to the male connector 18.

[0048] like Figure 12 and 13 As shown, a purge gas outlet 31 is provided on the side wall of the female interface inlet 28, and the external interface 26 of the female interface inlet 28 is in the form of a socket. The external interface 26 of the female interface inlet 28 is connected to the heating atomization module 5, and the purge gas outlet 31 is connected to the purge gas outlet connector 311. The male interface 18 is connected to the female interface inlet 28 to form the membrane desolvation interface inlet 10.

[0049] like Figure 10 and 11 As shown, the side wall of the sample outlet end 27 of the female connector is provided with a sensitizing gas inlet 29 and a purge gas inlet 30. The external interface 26 of the sample outlet end 27 is plug-in shaped and has an O-ring groove.

The male connector 18 is connected to the sample outlet end 27 of the female connector to form the membrane desolvation interface sample outlet end 12.

[0050] like Figure 14 , 15As shown in Figure 16, the male connector 18 includes an inner tube connector 21, an outer tube connector 22, and a male socket 23 connected in sequence. The outer tube connector 22 has a larger diameter than the inner tube connector 21 on the side closest to it. The inner tube connector 21 has an axially arranged sample gas channel 20, which is sealed to the inner sleeve of the membrane desolvation tube 11. An O-ring groove is provided on the outside of the inner tube connector 21, and an O-ring is placed inside the groove. The inner tube connector 21, in conjunction with the O-ring, achieves a sealed connection with the inner sleeve of the membrane desolvation tube 11. Multiple sets of gas guide grooves 24 are symmetrically arranged on the outer surface of the outer tube connector 22, which connects to the outer sleeve of the membrane desolvation tube 11. The male socket 23 is used to connect to the female socket 25 of the female connector 19, forming an annular purge gas chamber 32 between the male socket 23 and the female socket 25.

[0051] The membrane desolvation tube 11 includes an inner sleeve and an outer sleeve, forming an annular channel between them.

Dry argon purge gas flows into the external purge gas path from the purge gas inlet 30, blowing and carrying the solvent in the membrane dissolution tube out of the membrane dissolution tube 11 from the purge gas outlet 31. The purge gas flows in the opposite direction to the sample gas, so that the sample gas in the inner sleeve is dry at the sample outlet.

[0052] The working principle of this utility model is as follows: the liquid sample is atomized into a gaseous sample by the micro concentric nebulizer 6, and heated in the heating furnace 7 to maintain its gaseous state before being input into the membrane desolvation module 8. The gaseous sample is then heated in the membrane desolvation module 8, and the solvents such as water vapor in the sample seep from the inner tube of the membrane desolvation tube 11 to the outer tube, and are carried by the countercurrent purge gas to the waste gas condensation module 14 for condensation, so that the sample input into the mass spectrometer is a gaseous dry sample.

[0053] In this embodiment, the stability of a Ce single-element solution with a concentration of 10 μg / L was tested using membrane desolvation-inductively coupled plasma mass spectrometry (MD-ICP-MS) to verify the function of the exhaust gas condensation module 14. The same membrane desolvation device was used in the experiment. Ce elemental analysis was performed with and without the exhaust gas condensation module activated. Specifically, sample signal values ​​were acquired every 2 minutes for a total of ten consecutive acquisitions, and the short-term signal stability (RSD) of the sample within 20 minutes was calculated. The experimental results are shown in Table 1.

[0054] With the exhaust gas condensation module turned on, the stability RSD of the membrane desolvation device was 3.99%, which was 0.74 percentage points higher than the RSD of 4.73% when the exhaust gas condensation module was not turned on.
