Abstract
A method is descirbed for the analysis of any single volatile organic agent within 15 to 60 seconds in gas, blood, or tissue samples [long dash]interchangeably. Extraction procedures and chromatographic separations are avoided; since, in the vast majority of instances, only a single volatile agent is administered. The conditions for operation of the flame ionization detector are the same for all volatile organic agents, and the determination of any agent may be performed in sequence with other agents. Standardization may be carried out with water solutions of each agent; or all agents may be standardized against pure cyclopropane as a primary standard. Techniques are described for the anaerobic transfer and storage of specimens in core solder without loss of anesthetic vapor for periods of 2 to 3 weeks. Complex mixtures of anesthetic vapors may be analyzed by addition of appropriate chromatographic columns; however, the instrumental analysis time may be increased by one to 3 minutes.
