Analysis of Formaldehyde and Acetaldehyde in Ambient Air Using Integrated HPLC System

User Benefits

- Analysis of formaldehyde and acetaldehyde can be performed according to the Manual for measuring harmful air pollutants under air pollution control act. - Highly robust analysis can be performed using integrated HPLC system i-Series LC-2070C and chemically durable analytical column Shim-pack Scepter C18-120.

Introduction

Aldehydes are emitted into the atmospheric environment through various production activities and automobile exhaust gas. Analytical methods and allowable levels for these aldehydes in ambient air have been established both domestically and internationally due to concerns about environmental pollution and human health impacts. Specifically for formaldehyde and acetaldehyde, analytical methods are described in Manual for Measuring Harmful Air Pollutants under Air Pollution Control Act (described in only Japanese). i-Series LC-2070C high-performance liquid chromatograph is suitable for routine analysis because of its compact design for integrating all HPLC units and easy maintenance. Shim-pack Scepter series HPLC columns are packed with a fully porous organosilica hybrid material, providing excellent durability and performance across a wide range of conditions. This article presents an analysis of formaldehyde and acetaldehyde in ambient air using 2,4-dinitrophenylhydrazine (DNPH)-derivatization HPLC method with LC-2070C and Shim-pack Scepter C18-120. This method uses a DNPH cartridge to collect and derivatize aldehydes in ambient air. Subsequently, the aldehydes in the eluate from the cartridge are quantified and converted to concentrations in ambient air.
