Simultaneous trace analysis of nitrous oxide and halothane in air
British Journal of Anaesthesia
|March 1, 1978
Summary
A new gas chromatographic method accurately analyzes halothane and nitrous oxide in operating rooms. This technique helps assess anesthetic exposure for personnel safety.
Area of Science:
- Analytical Chemistry
- Occupational Health
Background:
- Operating theatre atmospheres can contain anesthetic gases.
- Monitoring anesthetic gas levels is crucial for personnel safety.
Purpose of the Study:
- To develop and evaluate a gas chromatographic method for simultaneous halothane and nitrous oxide analysis.
- To assess personnel exposure to anesthetic agents.
Main Methods:
- Gas chromatography with flame ionization detection (FID) for halothane.
- Gas chromatography with frequency-modulated electron capture detection (ECD) for nitrous oxide.
- Dynamic technique for standard preparation.
Main Results:
- FID is suitable for halothane analysis down to one part per million (p.p.m.).
- ECD shows high sensitivity to nitrous oxide but is non-linear between 25-1000 p.p.m.
- The overall reproducibility of the method is approximately 4%.
Conclusions:
- The developed gas chromatographic method enables simultaneous analysis of halothane and nitrous oxide.
- Analysis of end-expired gas effectively assesses personnel exposure to anesthetic agents.
