Abstract
Improved gas sample preprocessing is provided for scanning optical spectroscopic analysis instruments by tailoring characteristic gas handling times to the scan time Tof the analysis instrument. In particular, for sample preconcentration, the desorption duration Tof the sample preconcentrator should be ≥2T. For gas chromatography, the elution duration Tof relevant eluted species should be ≥2T. This advantageously avoids having significant changes in the gas sample within the analysis instrument as a scan is being performed.
