Development and evaluation of reaction gas chromatograph as a calibration method using an index compound

Abstract

In order to realize a technique that serves as a calibration method using an index compound, reaction gas chromatography was examined. An index compound represents a group which includes many compounds; compounds in this group can be calibrated using the index compound. The gas chromatograph/micro reactor/mass spectrometer (GC/MR/MS) consists of a capillary gas chromatograph/mass spectrometer and a micro reactor. By using the MR, alkenes and alkynes were transformed to alkanes having the same carbon skeleton. Ethylene in a cylinder was determined using ethane as an index compound. The results showed good agreement with a reference value. The hydrodechlorination of chlorobenzenes was examined. Chlorobenzene in a solution was determined by using benzene as an index compound. The experimental results and reference concentration showed a good agreement. The efficacy of this technique was demonstrated with these results.
