Application Note

Analysis of Trimethylamine in Exhaust Gas of Station Pollution Source by HS-GC/NPD

Introduction

Trimethylamine (TMA) is a volatile organic compound known to be a major contributor to malodor pollution. Created in a gaseous form as a result of the manufacture, use and disposal of materials utilized in sewage treatment plants, the low odor threshold of TMA results in regular poor air quality complaints of residents living near treatment plants.

In this application note, a method for the analysis of TMA in the exhaust gas of a station pollution source is presented. Utilizing a PerkinElmer TurboMatrix HS-40 sampler and a Clarus® GC with nitrogen phosphorus detector (NPD), TMA is detected with MDLs well below the standards developed by US and Chinese regulatory bodies.
