Removing Trace Contaminants from Sampling Cylinders.

Abstract

Three methods for removing trace contaminants from stainless-steel sampling cylinders were evaluated: evacuation, helium flushing, and steam flushing. Background and postcleaning concentrations were ascertained by gas chromatographic analyses for four hydrocarbons. From these data, washout curves were generated showing that steam flushing was the most effective method for the worst-case conditions.
