The applicability of the compound independent calibration method for the chromatographic analysis of four trihalomethanes (THM) after detection with a Microwave Induced Helium Plasma Atomic Emission Detector (MIP) was studied. The approach used was based on comparison of calibration curves constructed for the THM after monitoring the MIP signal at a carbon emission line and a chlorine emission line. The results of these studies also allowed evaluation of the usefulness of the MIP detector for the analysis of the THM at typical concentration levels of environmental concern.
