Abstract
Detection of monobasic, straight-chain saturated fatty acid (octadecan oic C18:0) in CCl4, based on the thermal lens effect after excitation by CO2 laser radiation at 934.9 cm(-1), is described for the first tim e. The achieved limit of detection (LOD = 0.3%) is comparable to that of the transmission infrared technique. Possibilities for further impr ovements in sensitivity and detection limit are also discussed.
