Analysis of Lower Aliphatic Aldehydes using Nexis GC-2030

Introduction

Lower aliphatic aldehydes are known to be associated with sick building syndrome. Thus various regulations require strict control of their concentrations. A common method of analyzing lower aliphatic aldehydes is to utilize 2,4-dinitrophenylhydrazine (DNPH) derivatization. Trace level analysis of these compounds is then enabled by using a flame thermionic detector (FTD/NPD). In this applications news, methods for collecting aldehydes in atmospheric air, extraction and elution using commercially available cartridges and the analysis of lower aliphatic aldehydes using GC-2030 with FTD-2030 are described.
