IDEMA STANDARDS . Microcontamination Document No. M11-99. Page 1of 6. General Outgas Test Procedure by Dynamic Headspace Analysis Description Purpose This document describes a general procedure for dynamic headspace analysis. This procedure can be applied to quantitatively and qualitatively measure the material purged from the space inside a chamber that contains disc drive piece parts and or sub- assemblies. The test is not designed to sample all of the material that could outgas from a particular part at a given temperature, but, rather to provide a snapshot of the outgassing performance of a material under certain conditions that may be duplicated so as to make it possible for multiple laboratories to obtain similar results on similar materials when performing this test. Scope This procedure describes the use of GC-MS as a detection method. Two methods for quantification are described. One method is semi-quantitative and utilizes an external hexadecane standard and applies a common response factor (of the hexadecane) to a number of compounds.
