摘要: A gas chromatography system comprising a sample introduction device, an oven coupled to the sample introduction device and a detector coupled to the oven is disclosed. In certain examples, the oven may be configured to receive a chromatography column in a space in the oven. In some examples, the oven may be constructed and arranged to provide a substantially constant temperature to the space during an analysis stage of the gas chromatography system.

摘要: A system for interfacing a sampling device and a chromatograph and for pre-concentrating analytes in a sample prior to introducing the sample into the chromatographic column is generally disclosed comprising an interface housing with a first channel and an adsorbent housing with a second channel, which contains at least one adsorbent. Valveless conduits permit fluid to be communicated between the sampling device and the first channel, between the first channel and the second channel, and the first channel and the column. In some embodiments, fluid flows in one direction when the analytes are adsorbed and in the opposite direction when analytes are desorbed. In certain embodiments, two different adsorbents are disposed in the second channel to adsorb different types of analytes.

摘要: Methods and systems for cooling gas chromatography ovens that comprise a housing having a fluid entry and a sleeve positioned within the housing to provide a fluid gap between the inner surface of the housing and the outer surface of the sleeve, where the sleeve is coupled to the fluid entry, and where a cooling fluid from the fluid entry traverses the inner layer of the sleeve and thereafter the outer layer of the sleeve via the fluid gap. In one embodiment, the housing includes at least one adjustable fluid exit, and the fluid gap is in fluid communications with the fluid exit(s). The fluid entry and the sleeve can be concentric, and the sleeve can include a heating element. A fan can be positioned to drive the cooling fluid from the fluid entry.

摘要: A polymeric interlocking tile for an adhesive-free assemblage with adjacent tiles having substantially similar, but inverted, edge interlocks thereon. The interlocks on each edge of a tile include a row of first and second sets of male-female types of alternating interlocks. The first interlock set includes a male lug projection having sidewalls forming one sidewall of a channel of U-shaped cross-section. The channel forms a female interlock cavity for the first set. The second interlock set is contiguous to the first set and includes a male projecting rib having two parallel sidewalls, one sidewall faces the edge and forms an opposite sidewall of the channel and an opposite, inwardly facing sidewall forms an enclosure for a second female cavity of the next set. At the opposite ends of each interlock row, the U-shaped channel sidewalls are wider to facilitate an initial interlock meshing between contiguous tiles of the assemblage.
