Description:
The principal properties related to analyte recovery in a vacuum distillate are boiling point and relative volatility. The basis for selecting compounds to measure the relationship between these properties and recovery for a vacuum distillation is presented. Surrogates are incorporated into samples, and their recoveries are shown to accurately predict experimental recoveries of other analytes. The accuracy of the surrogate-based recovery predictions, as compared with experimental results, typically exceeds 95% for water and soil test samples and can be used to correct analytical results for matrix effects.
