Samples obtained from the Hanford single shell tanks are contaminated with normal paraffin hydrocarbon (NPH) as hydrostatic fluid from the sampling process or can be native to the tank waste. The contamination is usually high enough that a dilution of up to several orders of magnitude may be required before the sample can be analyzed by the conventional purge and trap concentration followed by gas chromatography/mass spectrometry methodology. This can prevent detection and measurement of organic constituents that are present at lower concentration levels. To eliminate or minimize the problem, a sample cleanup method has been developed and validated and is presented in this document.
