Several techniques are available today for measuring gaseous pollutants from diesel exhaust such as carbon monoxide, carbon dioxide, nitric oxide, nitrogen dioxide, and sulfur dioxide. Four gas-sensing techniques are discussed: electrochemical, infrared, detector tubes, and passive samplers. For each technique, the general operating principles are described, and a discussion of measurement range, response time, accuracy, interferences, power requirements, life, and cost is included. Selecting the most appropriate technique is challenging. Each of the four techniques have benefits and shortcomings that must be evaluated in light of the sampling objective. At present, no "recommended" sampling or measurement protocol is available. A complete discussion of the problem of measuring gases present in diesel exhaust would require several large volumes. This paper is intended as an introduction to the problem.
