Abstract

The construction of photometric detector prototypes of gas chromatography is described. These prototypes were designed to monitor “cold” chemiluminescence phenomena such as the reactions of O 2 analyte with P 4 vapor or the reaction of organic compounds with O 3. They have also been used, via the quenching of chemiluminescence, to detect the passage of organic compounds through steady “cold flames”, generated by such systems as P 4/O 2 or SiH 4/O 2. An example of their selectivities as compared to standard flame-ionization detection response is given and some further developments are suggested.
