Determination of Trimethylamine in Air by Headspace Gas Chromatography

Determination of trimethylamine in air by headspace gas chromatography Details:



Name: HH-Tamine60 methylamine special capillary column

Specification: 60m * 0.32mm

*High service temperature: 280 ° C

No.: 20220109001



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. collects trimethylamine in the air; Transfer the adsorbent particles in the sampling tube after sampling to the headspace bottle, add saturated alkali solution, seal the headspace bottle immediately, and keep the water bath temperature constant for 30-40 min under certain conditions until the headspace bottle reaches the gas-liquid phase equilibrium state; With the standard solution of trimethylamine as reference, adopt headspace sampling and gas chromatography nitrogen phosphorus detector (GCNPD) for analysis. Calculate the content of trimethylamine in the sample according to the standard curve of standard concentration and peak area
