A METHOD AND APPARATUS FOR AUTOMATICALLY DETERMINING VOLATILE ORGANIC COMPOUNDS (VOCS) IN A SAMPLE

摘要

The present invention relates to a method and system for automatically determining volatile organic compounds (VOCs) in a sample by inputting the sample into a chamber, emitting infrared light from an optical light source into the chamber with the sample, detecting at a detector a detected infrared light from the chamber, transforming the detected infrared light to a Fourier Transform Infrared (FTIR) spectrum of the sample at a processor, wherein the FTIR spectrum has wavenumbers between 670 and 800cm-1, and processing the FTIR spectrum to determine each of the VOCs in the sample.
