Standard Test Method for Analysis of AMS (α-Methylstyrene) by Capillary Gas Chromatography
|Publication Date:||1 December 2012|
|ICS Code (Physicochemical methods of analysis):||71.040.50|
This test method covers the determination of the purity of AMS (α-methylstyrene) by gas chromatography. Calibration of the gas chromatography system is done by the external standard calibration technique.
This test method has been found applicable to the measurement of
impurities such as cumene, 3-methyl-2- cyclopentene-1-one,
acetophenone, 1-phenyl- 1-butene, 2-phenyl-2-propanol,
In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This standard does not purport to address all 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.
