Claim 10:
11. A method comprising:
moving a sample container from a sample tray to a sampling platform of an autosampler system with a pickup tool of the autosampler system, wherein the autosampler system further includes:
an x-axis rail;
a y-axis rail;
a z-axis rail; and
one or more motors coupled to the pickup tool, the one or more motors configured to traverse the x-axis rail, the y-axis rail, and the z-axis rail of the autosampler system,

moving, with the pickup tool, a sample wand fluidly coupled to a sample preconcentrator of the autosampler system to the sample container;
drawing, with the sample wand using a vacuum reservoir, a known mass of a gas sample having a volume in a range of 1-2500 cc from the sample container without addition of another gas into the sample preconcentrator, wherein the gas sample is at a pressure that is greater than, less than, or equal to atmospheric pressure while contained in the sample container;
analyzing the gas sample with a chemical analysis device fluidly coupled to the sample preconcentrator; and
while the sampling wand is disposed in a sampling wand cradle, the sampling wand cradle coupled to a vacuum source, drawing, with the vacuum source, a vacuum in the sampling wand.
