4.1 The purpose of this test method is to define a procedure for testing electropolished stainless steel components being considered for installation into a high-purity gas distribution system. Application of this test method is expected to yield comparable data among components tested for the purposes of qualification for this installation. FIG. 1 Ionic/Organic Contribution

1.1 This test method establishes a procedure for testing components used in ultra-high-purity gas distribution systems for ionic and organic surface residues. 1.2 This test method applies to in-line components containing electronics grade materials in the gaseous form. 1.3 Limitations: 1.3.1 This test method is limited by the sensitivity of the detection instruments and by the available levels of purity in extracting solvents. While the ion and gas chromatographic methods are quantitative, the Fourier transform infrared spectroscopy (FTIR) method can be used as either a qualitative or a quantitative tool. In addition, the gas chromatography (GC) and FTIR methods are used to detect hydrocarbons and halogenated substances that remain as residues on component internal surfaces. This eliminates those materials with high vapor pressures, which are analyzed per the total hydrocarbons test, from this test method. 1.3.2 This test method is intended for use by operators who understand the use of the apparatus at a level equivalent to twelve months of experience. 1.4 The values stated in SI units are to be regarded as the standards. The inch-pound units given in parentheses are for information only. 1.5 This standard does not
purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to use.
