The content of decomposable organic carbon compounds present in a gaseous phase is determined down to the parts per billion (10.sup.-9) range and in special cases down to the parts per trillion (10.sup.-12) range. The gaseous sample material being tested is introduced into a limited quantity of water wherein the organic compounds are photolytically decomposed. The decomposition products are ascertained in the carrier gas and/or in the limited quantity of water.
