| Abstract |
Optimization of a HERL-designed 1-L closed-loop-stripping (CLS) system, using variations of sample water bath temperatures and purging times, was accomplished by spiking five 1-chloroalkanes (C6, C8, C12, C16, and C18) into low organic Milli-Q reagent water to determine the recovery efficiency of each. Once operating conditions of purging time and water bath temperature were determined, on the basis of optimum recovery of the 1-chloroalkanes, recovery studies of a 22-compound standard mixture of organics were initiated by using two 1-L CLS devices of different design. This report supports previous CLS applications papers (2-4) demonstrating that CLS-capillary column GC/MS is an excellent method to measure many toxic organics in drinking water and in groundwater. For quantitative results, recovery efficiencies of individual compounds must be determined in the same matrix as the sample matrix. |
