A method for separating, or removing, particulate material, e.g., blood cells, from a sample of fluid, e.g., whole blood of a patient, in which the particulate material is suspended. In the case of separating blood cells from blood plasma or blood serum, the resulting samples of blood plasma or blood serum can be used for in vitro diagnostic applications. In normal practice, a whole blood sample of a patient are provided and then introduced into an apparatus that contains a flow channel. An acoustic field, which contains acoustic standing waves from external ultrasonic transducers, is located within the flow channel. Laminar flow is maintained in the flow channel. Blood cells and platelets are separated from blood plasma or blood serum at the end of the flow channel and collected. The method described herein allows fluid components to differentially migrate to areas of preferred acoustic interaction. The parameters that affect separation of particles are size, density, compressibility of the particles, and the fluid surrounding the particles.

A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

A blood analysis device for centrifugally separating plasma in a channel, wherein conveyance of blood, plasma and calibration liquid is effected within the device without using a pump or the like. The calibrator solution is reliably discharged from a sensor portion so as to make high precision analysis possible. A sensor section is provided in a plasma separating section and disposed on the side associated with a first centrifugal pressing direction as seen from a blood reservoir and a calibrator solution reservoir, while a calibrator solution waste reservoir is disposed in a second centrifugal pressing direction as seen from the plasma separating section (sensor section). The calibrator solution is conveyed to the sensor section by centrifugal operation in the first centrifugal direction. After sensor calibration, the calibrator solution can be reliably discharged from the sensor section by effecting centrifuging in the second centrifugal direction. After the calibrator solution discharge, centrifuging is effected again in the first centrifugal direction, thereby conveying the blood in the blood reservoir to the sensor section and effecting separation of blood cells and plasma. In the case of providing a plurality of sensors, a blood introducing channel from the blood reservoir is branched downwardly of a sensor groove for communication, with the blood cells being fractionated in the branch section. The individual sensors can be isolated from each other by blood cell fraction, making higher precision analysis possible.

A separatory material comprising a composite material containing a stimulus-responsive polymer and a substance interacting specifically with a target substance, wherein said stimulus-responsive polymer undergoes a structural change upon a physical stimulus so that the interaction of said substance interacting specifically with the target substance is affected by the chemical or physical environmental change, thereby causing a reversible change in the interaction force with the target substance due to the physical stimulus, which separatory material is characterized in that said stimulus-responsive polymer has no affinity with said substance interacting specifically with the target substance.

A method and apparatus for analyzing samples using mass spectrometry are disclosed. The apparatus includes a reaction device configured to dissociate sample ions into fragments by reacting the sample ions with a charged species (e.g., electrons) such as through ECD, EID, or EIEIO.

The fragments may include radical fragments and non-radical fragments. The apparatus may also include an oxygen gas source configured to react with the radical fragments to produce oxygen-radical fragments. Spectra resulting from analysis of the fragments may allow for the determination of the oxygen-radical fragments resulting from the dissociation of the sample molecules.

A crop harvesting header includes a cutter bar arranged across a forward edge, a draper or auger transport arrangement for transporting the cut crop, and a reel mounted on reel arms having a plurality of reel bats at spaced positions around the reel axis each reel bat having reel fingers projecting generally radially outwardly from the reel axis. Each bat is mounted for pivotal movement about its bat axis. At both ends of each bat is mounted a crop divider which pivots with the bat and is formed with a plate lying in a radial plane of the bat with angularly spaced fingers around the outer edge. A leading edge of the plate and front finger is convexly curved relative to the concave curve of the front edge of the finger and is angularly advanced relative to the leading edge of the adjacent fingers such that the rotating crop dividers on the reel co-operate with a stationary crop on the header to separate the cut crop from uncut crop passing alongside the end of the header.

A flow velocity measuring device is able to conduct a fluid to a sensor element after removal of dust and dirt contained in the fluid to accurately measure the flow velocity of the fluid even when the fluid is low in flow velocity and the device is mounted in any direction.

A method apparatus for removing a casing, particularly a casing with a clip end embedded in the product, is disclosed where the clipped end is clamped and gas is injected into this end to blow out the clip and casing end while the clamped portion prevents the entire casing from being inflated. The air or gas, such as HEPA filtered air, is injected into the product with a needle, for instance, to balloon out the casing in the clamped area to free the previously embedded clip. The clip is then gripped, certain cuts are made in the casing, and the casing is pulled from the product. An injector such as a needle is inserted into the end portion of the product and pressurized gas, such as HEPA filtered air, is injected into the end portion. The injection of the gas causes the casing to balloon out from the product thereby freeing the previously embedded clip. The freed clip is then gripped while the casing is then cut for removal. The casing may be cut in a Y-shape with two cuts beginning approximately at two corners of one side of the square end and angled towards each other along a side of the product. The two cuts meet, and a third cut is made longitudinally along the length of the product beginning at the meeting point of the two angled cuts. The gripped clip and casing are pulled causing the casing to separate from the product along the cut lines.
