Determination of trimethylamine in ambient air by GC-MS with HH-Tamine60 capillary preconcentration system
Analysis of trimethylamine in ambient air by GC-MS with HH-Tamine60 methylamine dedicated capillary preconcentration system Details:
Trimethylamine is a flammable and highly corrosive gas with fishy ammonia odor. It is soluble in water, ethanol and ethylene mi. They are the main raw materials for the production of dyes, drugs, organic nitrogen pesticides, fried yao, and surfactant vulcanization accelerators. Trimethylamine belongs to the odor pollutant with du, and is one of the main objects of odor pollution control, with the olfactory threshold concentration of 0.0001ppm. The odor control standard of China stipulates that the limit standard of trimethylamine is 0.05-0.45mg/m3.
The method has high sensitivity and good linear relationship The results showed that when the column temperature was 140 ℃, the sample inlet temperature was 180 ℃, the detector temperature was 180 ℃, and the nitrogen flow rate was 30mL/min, the average recovery rate was 100 3%, and the relative standard deviation was 3%
