Summary

Gas chromatography with an electron-capture detector has been used to determine tetracarbonylnickel and pentacarbonyliron in synthesis gas. Critical parameters such as the temperatures of the detector and the column, the stabilities of the metal carbonyls in various gaseous matrices, the materials used for gas sample tubes, and the presence of hydrogen sulphide have been investigated. Both gaseous samples and solutions of metal carbonyls in isooctane have been used as calibration standards. The limit of detection for tetracarbonylnickel has been found to be about 0.001 ppmv and that for pentacarbonyliron somewhat less.
