Abstract
The presence of volatile metal carbonyls, e.g., nickel tetracarbonyl and iron pentacarbonyl, in fluid streams can be measured simultaneously by a gas chromatograph using squalane as the stationary liquid phase and a constant current, electron capture detector.
Claims3
A method of measuring the volatile metal carbonyl content of a fluid stream comprising,
- (a) obtaining a sample of the fluid stream,
- (b) feeding the sample with a carrier stream into an on-column glass column in a gas chromatograph wherein the components of the sample are separated, the column being operated at 23.degree.-40.degree. C. and containing squalane as the stationary liquid phase for separation, and
- (c) the stream from the glass column feeding into a constant current, electron capture detector where the metal carbonyl content is detected and a signal produced.
