Determination of Total Hydrocarbons in Air by Gas Chromatography
Gas Chromatographic Determination of Total Hydrocarbons in Air Details:

Name: Total Hydrocarbon Column

Stationary phase: silanized glass microspheres

Particle size: 60-80 mesh

Specifications: 2m*3mm, 2m*4mm, 2m*1/8

Model: Silanized glass microspheres

Application: Determination of ambient air/stationary pollution source waste gas gas chromatography

Non-methane total hydrocarbons (NMHC) refers to the sum of volatile hydrocarbons (mainly C2-C8) other than methane, and has long been an important indicator of ambient air monitoring.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. is researching and using gas chromatography to directly determine the rapid determination method of total hydrocarbons in the air at mg/m^ through on-site sampling. The method has high accuracy and precision, the correlation coefficient is above 0.999, the coefficient of variation is less than 0.3%, and the lowest detection limit is 0.14ng (calculated as methane).

The total hydrocarbon column developed by Haohan Chromatography: high column efficiency, no branching of total hydrocarbon, accurate and reliable quantification.
