便携式光电离色谱仪体积小而轻,携带方便,仪器带有可充电的蓄电池做电源(也可用220V电源),充有空气的小载气瓶以及超高灵敏度的光电离检测器(PID),对大气或水质中的多种挥发性污染物(电离能小于11.5eV)均能测定。例如挥发性的碳氢化合物乙烯、丙烯、丁烯、戊烷、环状化合物苯类等,含卤素的氯乙烯、氯仿、氯甲烷、三氯乙烯、氟氯碳化合物等;硫化氢、硫醇、烷基或芳基硫化物,无机物磷化氢、氨、肼、一氧化氮等。对硫化氢、苯环化合物等可以检测到0.1ppb。
Portable photoinduced chromatograph small and light, easy to carry, the instrument with a rechargeable battery power supply (also available 220V power supply), air filled small carrier and ultra-high sensitivity photoionization detector (PID) A variety of volatile contaminants in the atmosphere or water quality (ionization energy less than 11.5eV) can be measured. For example, volatile hydrocarbons such as ethylene, propylene, butylene, pentane, cyclic compounds such as benzene and the like, halogenated vinyl chloride, chloroform, methyl chloride, trichlorethylene, chlorofluorocarbons and the like; hydrogen sulfide, , Alkyl or aryl sulfides, inorganic phosphine, ammonia, hydrazine, nitric oxide and the like. For hydrogen sulfide, benzene ring compounds can be detected 0.1ppb.
