Abstract

Tunable Diode Laser Absorption Spectroscopy, operating in the near IR, is the best method available for making continuous measurements of many gases. The measurements are interference free and can be made with high sensitivity in fractions of a second. Sensitivities in the parts per billion range can be achieved for a number of gases such as CO, CO₂, HF, HCl, CH₄, C₂H₄, C₂H₂, O₂, NH₃, HCN, H₂S.
