根据日本《工业安全与健康法》的规定，在小玻璃管产品中通常使用活性碳作为取样剂，用于测量工作环境中的有机溶剂蒸气浓度。从活性碳中吸附有机溶剂水蒸气的萃取效率对测量准确度有很大影响。我们考察了日本典型取样管产品中使用的活性碳的性能，以及用相平衡法测定的对效率的影响。本研究重点研究了N_2-BET比表面积、粒径和前驱体材料。
Activated carbon is commonly used as a sampling agent in small glass tube products for the measurement of organic solvent vapor concentrations in the work environment as established by the Industrial Safety and Health Act in Japan. The extraction efficiency of adsorbed organic solvent vapor from the activated carbon significantly affects the measurement accuracy. We have investigated the properties of activated carbon used in typical Japanese sampling tube products, and the effects on the efficiency as determined by the phase equilibrium method. This study focused particularly on N2-BET specific surface area, grain diameter and the precursor materials of the activated carbon.
