Claim 5:
6. A system comprising:
a sample container having a volume in a range of 1-2500 cc containing a gas sample at a pressure that is greater than, less than, or equal to atmospheric pressure; and
an autosampler system comprising:
a sampling platform;
an x-axis rail;
a y-axis rail;
a z-axis rail;
a pickup tool coupled to one or more motors configured to traverse the x-axis rail, the y-axis rail, and the z-axis rail, wherein the pickup tool is configured to move a sample container from a sample tray to the sampling platform; and
a sample wand configured to draw a known mass of the gas sample from the sample container into a sample preconcentrator fluidly coupled to the sample wand without addition of another gas using a vacuum reservoir, wherein the pickup tool is further configured to move the sample wand to the sample container and 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;
a chemical analysis device fluidly coupled to the sample preconcentrator; and
a sampling wand cradle, the sampling wand cradle coupled to a vacuum source such that a vacuum is drawn in the sampling wand while the sampling wand is disposed in the sampling wand cradle.
