Abstract
Dual beam thermal lens spectrometry was applied (at 965 cm-1) for the first time to determine the content of trans unsaturated fatty acids in margarine. An improvement in sensitivity (LOD = 0.002%) of more than two orders of magnitude in comparison with traditional infrared technique was achieved.
