| Abstract |
A test method for halogenated hydrocarbons has been evaluated and information is provided for the user. Four compounds were investigated, methylene chloride, methyl chloroform, Freon 113 and ethylene dibromide. Cylinder gases used for calibration and auditing were tested for stability. Decreases in concentration of 3-4% per month were observed. Tedlar and aluminized Mylar containers were also tested. Tedlar bags were found to be superior, maintaining Freon 113 samples stable for 10 days, methyl chloroform for 7 days, methylene chloride for 6 days and ethylene dibromide for 2 days, at room temperature. Heating caused decreases in stabilities. Heated ethylene dibromide samples were more stable in aluminized Mylar than in Tedlar. A procedure was developed to remove persistent residues from Tedlar bags that had contacted high concentrations of halogenated hydrocarbons. Information is also included on gas chromatographic columns for use in this method of analysis. |
