Annotation: A gas chromatographic procedure for the determination of carbon monoxide in blood was improved by using a capillary system in combination with a micro thermal conductivity detector.
Abstract: The technique involved the use of a capillary Molecular Sieve column in combination with a Micro Thermal Conductivity Detector. This system is very sensitive with high resolutions. The analytical time is reduced to approximately 2 minutes. This amounts to a reduction of the analytical time by a factor of two to four in comparison with methods described by others. In addition to a rapid analysis, it is also possible to reduce the liberation time of 40 minutes. Using sulfuric acid as the liberating agent, a gradual and reproducible release of carbon monoxide was seen. This approach shortens the time required in emergency cases to prepare a sample.
