工作場所空氣中甲醇檢測填充柱
工作場所空氣中甲醇檢測填充柱 詳細(xì)信息：

甲醇是無色透明、具有高度揮發(fā)性的液體，易與水、醚及大多數(shù)有機(jī)溶劑混溶。在醫(yī)藥、化工等產(chǎn)品的生產(chǎn)過程中作為原料、溶劑被廣泛使用。甲醇在人體內(nèi)氧化為甲醛、甲酸，具有很強(qiáng)的毒性，尤其對視神經(jīng)的毒性作用大。一次攝入4g以上，即可引起急性中毒，致盲劑量約7-8m1，致死劑量為30-40m1。長期少量攝入可導(dǎo)致饅性中毒，除頭痛、頭暈、消化(digestion)功能紊亂(chaos)外，其特征性的臨床表現(xiàn)為視野縮小及不能矯正的視力減退。因此，必須對一些使用甲醇的作業(yè)場所空氣進(jìn)行監(jiān)測，從而保護(hù)從業(yè)人員的身體健康。

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.
