Abstract
An experimental method that combines use of a CW CO2 laser with a non- resonant photoacoustic cell operating at high temperature has been use d to detect the content of total organic carbon in soil water solution s by means of CO2 concentration measurements. Detection sensitivity of about 4 mmol l-1 for total organic carbon has been achieved at a cell temperature of 775 K.
