Abstract

Soil sampling and storage practices for volatile organic analysis must be designed to minimize loss of volatile organic compounds (VOCs) from samples. The En Core® sampler is designed to collect and store soil samples in a manner that minimizes loss of contaminants due to volatilization and/or biodegradation. ASTM D 6418, Standard Practice for Using the Disposable En Core® Sampler for Sampling and Storing Soil for Volatile Organic Analysis, describes the use of the En Core® sampler to collect and store a soil sample for volatile organic analysis.

To support the ASTM practice, a study was performed to estimate the precision of the performance of the En Core® devices to store soil samples spiked with low concentrations (<200 µg/kg) of VOCs. Data generated in the precision validation study show good precision of the performance of the samplers to store soil samples containing low concentrations of a variety of VOCs.
