compound in both the gas phase and the sample becomes
smaller, although the ratio remains constant. The logs of the
peak areas versus the extraction number are plotted to obtain
quantitative data about the compound of interest.
MHE is often used as a calibration tool. Once the peak area
versus the concentration is established for a given sample
matrix, quantitative measurements of samples with a similar
matrix can be carried out using a single extraction.
