1.4 In order to accommodate analysis of a variety of sample matrices and VOCs, a matrix modifier (Sec. 7.7) is generally recommended to be used with this method. The matrix modifier is a water soluble salt solution that is added to each sample and standard vial prior to analysis.
Purge and Trap. Purge and Trap (P&T) analysis combines high-sensitivity detection of volatile organic compounds (VOC) in water, wastewater, soils, and sludges with low carryover. The P&T instruments from Teledyne Tekmar, a world leader in Purge and Trap Sample Preparation Systems, accommodate many regulatory and standard methods (EPA, ASTM).
