Gas analysis system providing simultaneous analysis and multi-point sample acquisition

摘要

A gas handling system capable of simultaneous sample analysis and multi-point sample acquisition is provided. An exemplary system has N gas inlets and N+1 sample storage loops (having a high aspect ratio), where N≧2. The high aspect ratio of the sample storage loop prevents significant sample diffusion along the length of the loop. Therefore each loop preserves a time axis for its contents. The sample loops can be disposed to simultaneously admit samples from different points in space. A gas switching manifold can be employed to connect the sample storage loops sequentially and one at a time to the gas analysis instrument for analysis. A common time axis for all samples can be reconstructed from the switching and flow conditions. Thus a simultaneous multi-point measurement using a single analysis instrument is provided.
