Title: Applicability of the Compound Independent Calibration Method for the Chromatographic Quantitation of Trihalomethanes with Atomic Emission Detection
Author: Augusto, Fabio
Valente, Antonio Luiz Pires
Abstract: 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.
Foi estudada a aplicabilidade do método de calibração independente de composto para a análise cromatográfica de quatro trialometanos (THM) com detecção por um Detector por Emissão Atômica em Plasma de Hélio Induzido por Microondas (MIP). A sistemática usada se baseou na comparação de curvas de calibração construídas para os quatro THM monitorando o sinal nas raias de emissão de cloro e carbono. Os resultados desses estudos também permitiram avaliar a utilidade do detector MIP para a análise dos THM em concentrações ambientais típicas.
