1. A gas chromatography system comprising:
at least one gas chromatography subsystem including a first injector port and a second injector port;
an autosampler including:
a carousel tray mounted for rotation about a rotation axis, wherein the carousel tray is mounted above the first and second injector ports, and wherein the carousel tray includes:
an arcuately extending first row of sample reservoirs; and
an arcuately extending second row of sample reservoirs;
a first sample transfer tower to extract samples from the first row of sample reservoirs;
a second sample transfer tower to extract samples from the second row of sample reservoirs; and
a control system operative to:
selectively position the carousel tray relative to the first and second sample transfer towers to align the first sample transfer tower with a first sample reservoir in the first row and to align the second sample transfer tower with a second sample reservoir in the second row;
simultaneously draw a first sample from the first sample reservoir using the first sample transfer tower and a second sample from the second sample reservoir using the second sample transfer tower; and sequentially thereafter
simultaneously inject the first sample into the first injector port using the first sample transfer tower and the second sample into the second injector port using the second sample transfer tower.
