This Document defines a test method for determining organic compounds on the wetted surfaces of ultra high purity (UHP) chemical delivery systems and components.

This Test Method is applicable to UHP chemical delivery systems and components. Examples of test samples include valves, regulators, filters, and mass flow controllers, tubing, weld fittings, and face seal fittings.

This Test Method could also be used to determine the contamination contributed from an assembly or fabrication area.

This Document details the method to extract and measure organic contaminants present on the wetted surfaces.

This Test Method could be used to evaluate the effectiveness of various flushing or purging processes.
