Collaborative Study of Reference Method for the Continuous Measurement of Carbon Monoxide in the Atmosphere (Non-Dispersive Infrared Spectrometry),

摘要

Information obtained in the evaluation and collaborative testing of a reference method for measuring the carbon monoxide content of the atmosphere is presented. The method is based on the infrared absorption characteristics of carbon monoxide,using an instrument calibrated with gas mixtures containing known concentrations of carbon monoxide. The method as published in the appended 'Federal Register'article was tested by means of a collaborative test involving a total of 16laboratories. The test involved the analysis of both dry and humidified mixtures of carbon monoxide and air over the concentration range from 0to 60mg/cu m. A statistical analysis of the data of 15laboratories is presented. (Author)
