Simultaneous Analysis of DNPH-Derivatized Aldehydes Using Prominence™-i Plus and Shim-pack Scepter™ PFPP-120

Introduction

On September 21, 2018, the method for measurement of Specified Offensive Odor Substances in Article 5 of the Ordinance of Japan’s Offensive Odor Control Law was revised, and was promulgated and enforced as Ministry of the Environment Notification No. 78. This revision newly added high performance liquid chromatography (HPLC method) for concentration measurement at the border of the site and flow rate measurement at the gas emission point of six aldehyde substances (Acetaldehyde, Propionaldehyde, n-Butyraldehyde, iso-Butyraldehyde, n-Valeraldehyde, and iso-Valeraldehyde). Here, we introduce an example of analysis of these six aldehydes using the Prominence-i Plus integrated high performance liquid chromatograph and the Shim-pack Scepter PFPP-120 column, which contains the pentafluorophenylpropyl (PFPP) group.
