AUTOSAMPLER AND GAS CHROMATOGRAPHY SYSTEM AND METHOD INCLUDING SAME

摘要

A gas chromatography system includes at least one gas chromatography subsystem including at least one injector port, and an autosampler. The autosampler includes a carousel tray mounted for rotation about a rotation axis and including arcuately extending first and second rows of sample reservoirs, a first sample transfer tower to extract samples from the first row, a second sample transfer tower to extract samples from the second row, and a control system operative to: selectively position the carousel tray relative to the first and second sample transfer towers to align the first and second sample transfer towers with a selected pair of the sample reservoirs of the first and second rows, respectively; draw samples from the selected pair using the first and second sample transfer towers; inject the sample drawn from the first row into the at least one injector port using the first sample transfer tower; and inject the sample drawn from the second row into the at least one injector port using the second sample transfer tower.
