CO laser infrared (IR) photoacoustic spectroscopy (PAS) at 1801 cm-1 was used to determine the content of carbonate in various soils. The PA signal is linearly proportional to the content of carbonate within the 0-30% (w/w) range; the 2% (w/w) limit of detection (LOD) is adequate for the application in practice.
