摘要： Disclosed is a chromatography column cylinder 200 formed from a polymer composite comprising an outer layer 220 and inner layer 210 intended to be in direct contact with the intended contents of the cylinder in a volume 202, wherein the outer layer supports the inner layer, for example when there is negative pressure in the volume 202. In one embodiment, one of said layers is molded directly onto a surface of the other layer such that there is no gap between the two layers. Disclosed also is a method for forming a chromatography column cylinder.

摘要： A multi-walled tube (100) comprising an inner tube (112), an intermediate tube (114) and an outer tube (116) that is useful as an analytical column in which chemical mixtures can be separated into their individual components is described. In order to be acceptable as an analytical column, the inner surface (112A) of the multi-walled tube must support effective separation, but not react chemically with or contaminate the solvent or the analyte (sample to be separated). Grade 316 stainless steel is typically preferred for this purpose. Moreover, the inner diameter (ID) surface of the multi-walled column is preferably very smooth (less than 10 micro inch Ra) with no interruptions in the surface such as scratches, pits, or asperities. However, since the column is designed to be attached to chromatographic equipment using standard size connection features, the size of standard fittings define the outer diameter (OD) of the column.

摘要： An apparatus for chemical separations includes a microfluidic substrate having an outlet aperture for outputting an eluent of a sample. An emitter assembly includes having a deformable end portion, an inlet near the deformable end portion to receive the sample eluent from the microfluidic substrate, and an electrically conductive outlet portion to emit a spray of the sample eluent. A force-applying unit applies a force to the emitter assembly that urges the deformable end portion into contact with the microfluidic substrate. The deformable end portion is more elastic than the microfluidic substrate so that the contact between the microfluidic substrate and the deformable end portion produces a substantially fluid-tight seal between the outlet aperture of the microfluidic substrate and the inlet of the emitter assembly.

摘要： A method for making conduits includes inserting an inner tube into an outer tube and melting a portion of the inner tube to form a bond with the outer tube. The inner tube includes a polymeric material and the outer tube includes a material having a greater yield strength than the polymeric material. A conduit includes one or more inner tubes at least one of which is melt-bonded to one or more outer tubes. An analytical instrument includes a separation column, a solvent reservoir and pump, a sample injector, a detector to observe an eluent of the separation column, and tubing to transport fluid between components of the instrument.

摘要： Pipe containing a tubular metal casing (29, 29') with an inlay (31) and sealing ring (35), which is characterised in that the inlay (31) is configured as a plastics material tube and is pushed or drawn into the metal casing (29, 29') and a sealing ring (35) consisting of plastics material is connected to the inlay (31) at the end. Because of said structure, a connection to further system parts is possible, which is carry-over- free, inert on the inside, liquid-tight, optionally gas-tight, and pressure-tight. Connection element and connection to connect the pipe to feed and/or discharge lines of a capillary system. Pipes, connection elements and connections of this type are advantageously used in low and high pressure systems, such as, for example, in an HPLC column. The use of such systems is advantageous in in-vitro diagnostics and in liquid handling applications.

摘要： An object of the present invention is to provide a various-substance holder, a various-substance holder treating apparatus, and a various-substance holder treating method which enable the mutual identification of a plurality of particulate carriers to which various substances are or can be immobilized without the need to arrange the particulate carriers at predetermined positions or in a predetermined order, eliminating the need for time and effort to arrange the various substance at predetermined positions or in a predetermined order to allow treatments to be quickly and easily achieved. The various-substance holder according to the present invention has a plurality of particulate carriers or plural sets of particulate carriers to which plural types of chemical substances are or can be immobilized and a carrier holding portion holding the plurality of particulate carriers or the plural sets of particulate carriers in a substantially stationary state such that the plurality of particulate carriers or the plural sets of particulate carriers can be externally measured. The various-substance holder is configured so that each of the plurality of particulate carriers or at least one of the particulate carriers belonging to the plural sets of the particulate carriers are labeled according to types of the chemical substances or for each of the particulate carriers or each set of the particulate carriers so as to be mutually identifiable before the particulate carriers are introduced and held in the carrier holding portion.
