工作场所空气中甲醇检测填充柱
工作场所空气中甲醇检测填充柱 详细信息：

甲醇是无色透明、具有高度挥发性的液体，易与水、醚及大多数有机溶剂混溶。在医药、化工等产品的生产过程中作为原料、溶剂被广泛使用。甲醇在人体内氧化为甲醛、甲酸，具有很强的毒性，尤其对视神经的毒性作用大。一次摄入4g以上，即可引起急性中毒，致盲剂量约7-8m1，致死剂量为30-40m1。长期少量摄入可导致馒性中毒，除头痛、头晕、消化(digestion)功能紊乱(chaos)外，其特征性的临床表现为视野缩小及不能矫正的视力减退。因此，必须对一些使用甲醇的作业场所空气进行监测，从而保护从业人员的身体健康。

浩瀚色谱（山东）应用技术开发有限公司，采用石墨化碳黑填充柱5%Carbowax 20M Carbopack B测定工作场所空气中甲醇，外标法定量，结果准确。

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.
