Analysis of Formaldehyde by the Derivatization- High Performance Liquid Chromatography Method, in Compliance with Water Quality Standards

Introduction

Revisions to the ministerial ordinance related to water quality standards were announced on March 30 2016 (Japan's Ministry of Health, Labour and Welfare Ordinance No. 115; enacted April 1 2016), and Ordinance No. 261 was partially revised. The derivatization-high performance liquid chromatography method was added therein as a formaldehyde inspection method. The standard value remains unchanged at 0.08 mg/L max. This article introduces an example of the analysis of formaldehyde in compliance with the derivatization- high performance liquid chromatography method (hereinafter the official method), using a Shimadzu Prominence-i high performance liquid chromatograph.
