The combination of gas chromatography and infrared spectroscopy using a flow liquid cell (II).

Abstract

Gas chromatography and infrared spectroscophy were connected by using a flow liquid cell to be applied. for a unit process in rapid analysis. By using tetrachloroethylene as the organic vapor instead of carbon tetrachloride, the application of this GC-IR combination method was extended to high boiling substances such as methyl benzoate, dimethyl adipate, methyl myristate, decanol, diphenyl ether etc. As every GC fraction was passing through the cell, consecutive scans were taken, or a portion of every sample was once trapped in the cell for measuring its infrared absorption in the range of 4000650 cm^-1. This new simple device permits the rapid spectrometric examination of GC effluents.
