ABSTRACT:
A liquid and gas analyzing system that provides a sample collecting probe that delivers the sample through inert materials to prevent any contamination. For gas analyzing for environmental monitoring process control, a sample collecting probe having a borosilicate glass tube liner connected through an inner spiral tube to the analyzer prevents contamination. The system then delivers the sample to a single pass radiated optical cell by a light beam. The light beam is collected by a miniature CCD array spectrometer and delivered to an industrial PC. The output from the industrial PC is then delivered to a software controlled data acquisition system for analysis. The system is constructed to be a modular in design allowing addition of complementary components for measuring and analyzing different materials. The system described can be used for extractive gas analysis as well as extractive liquid analysis for monitoring stack gases, environmental air or general environmental monitoring and with modifications for breath analysis and human saliva and blood testing. The system is also adaptable for long path remote sense gas monitoring of fence lines and for leak detection.
