Application Note

Meeting EU REACH Requirements using Chemical Ionization Gas Chromatography/ Mass Spectrometry

Clarus GC/MS for chemical product evaluation

Introduction

The EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation was adopted in 2006 with the aim of protecting human and environmental health, along with the competitiveness of the chemical industry within the European Economic Area. The regulation places responsibility for chemical product evaluation and compliance on manufactures and importers, as opposed to the government.

In this application note, a method utilizing a 爱游戏平台注册登录 Clarus® GC/MS for the analysis of 4,4’-Methylenebis(2,6-di-tert-butylphenol), also known as Ethyl 702, is described. The method fulfills the REACH requirement by using the ammonia adduct ion to confirm the compound molecular weight. Improved analytical results were obtained using a mass flow control (MFC) mechanism for the regulation of the CI reagent gas flow.
