The authors are in the process of modifying and validating analytical methods based on the original TO-14 method for application to the waste tanks. While SUMMA canisters are used for sample collection, when samples are sufficiently concentrated they are directly introduced to the GC/MS using a gas sampling loop injector. In addition, the SUMMA canisters are heated to insure that the sampled compounds remain in the gas phase. For more dilute samples, a microscale purge and trap method is used to dewater the samples during a cryogenic preconcentration step. The authors have successfully applied these methods to several tank samples. While still in the validation stages, preliminary data suggest that the authors will be able to use either the direct loop injection or microscale purge and trap cryogenic preconcentration for most samples.
