NIOSH mandates that trace gas analysis should be conducted using an infrared analyzer because this method allows for accurate and sensitive detection of anesthetic gases in the ambient air. Infrared analyzers work by measuring the absorption of infrared light by the gas molecules, which is proportional to their concentration in the air. This provides reliable data on the levels of potentially harmful trace gases, enabling healthcare facilities to monitor and maintain safe working conditions for staff and patients.

Colorimetric analyzers, while they have their uses, may not offer the same level of specificity and quantitative analysis that infrared analysis does. Personal sampling pumps, on the other hand, are typically used for sampling air but may not directly provide real-time analysis of trace gas concentrations. Visual inspection is inadequate as it does not offer precise measurements or the ability to detect gases that are colorless and odorless. Thus, the use of an infrared analyzer aligns with NIOSH's recommendations for effective monitoring of anesthetic gases in clinical environments.
