National, local, and industry standards use non methane total hydrocarbons to indicate the emission of volatile organic compounds. In the field of environmental monitoring, there are three main monitoring technologies for non methane total hydrocarbons: 1. laboratory manual monitoring, 2. on-site portable instrument monitoring, and 3. online continuous monitoring.
The MS5A methane column developed by Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has been applied in Tianrui VOCS online analysis of non methane total hydrocarbons. The column efficiency is high, the separation is good, oxygen does not interfere with methane peak, the quantification is accurate, and the results are satisfactory.
