Abstract:
A method of sampling and determining the presence of certain substances in a container comprising the steps of:injecting fluid into an opening in said container in order to displace at least a portion of the contents thereof to form a sample cloud at regions outside of the container adjacent the opening thereof;evacuating a sample of said portion of the container contents so displaced by applying suction to the sample cloud in said regions outside of the container;splitting the sample evacuated into first and second portions;providing a chemiluminescence detector for analyzing the first portion of the sample to determine presence or absence of contaminants of nitrogen containing compounds;said chemiluminescence detector including,means for heating the first portion of the sample evacuated; andmeans for mixing the heated sample portion with ozone to cause a chemical reaction therewith in order to generate chemiluminescence of the reactants;optically analyzing said chemiluminescence to determine presence or absence of said certain substances;illuminating the second portion of the sample with radiant energy to generate fluorescence in the sample; andanalyzing said fluorescence to determine presence or absence of aromatic hydrocarbon contaminants in the sample.
