Abstract
A new chemiluminescence detector for gas chromatography with selectivity for iodinated hydrocarbons is described. Emission from electronically excited iodine monofluoride formed in the reaction of the eluting compounds with the microwave discharge decomposition products of SF6 is detected by photon counting. The detector was found to have no significant response to a variety of aliphatic and aromatic compounds containing C, H, O, N, Cl and Br atoms; the only observed interference being a small response to olefinic hydrocarbons. It is expected that the detection limit of one microgram for alkyl iodides can be greatly improved by use of a cooled red-sensitive photomultiplier tube.Keywords
