Packed column for detecting methanol in the air of workplace
Packed column for detecting methanol in the air of workplace Details:

Methanol is a colorless, transparent, highly volatile liquid and is easily miscible with water, ether and most organic solvents. It is widely used as a raw material and solvent in the production process of medicine, chemical industry and other products. Methanol is oxidized into formaldehyde and formic acid in the human body, which has strong toxicity, especially the most toxic effect on the optic nerve. Ingestion of more than 4g at a time can cause acute poisoning, with a blinding dose of about 7-8ml and a lethal dose of 30-40ml. Long-term intake of small amounts can lead to steamed bun poisoning. In addition to headaches, dizziness, and digestion disorders (chaos), its characteristic clinical manifestations are reduced visual field and uncorrectable vision loss. Therefore, it is necessary to monitor the air in some workplaces where methanol is used to protect the health of employees.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses graphitized carbon black packed column 5% Carbowax 20M Carbopack B to determine the methanol in the workplace air. The external standard method is used to quantify the methanol and the results are accurate and reliable.
