型号：DC-550/Chromosorb W NAW DMCS
应用：GB/T 5750.8-2006 生活饮用水标准检验方法 有机物指标
被测水样置于密封的顶空瓶中，在一定的温度下经一定时间的平衡，水中的卤代烃逸至上部空间，并在气液两相中达到动态的平衡，此时，卤代烃在气相中的浓度与它在液相中的浓度成正比。通过对气相中卤代烃浓度的测定，可计算出水样中卤代烃的浓度。

Name: Packed Column
Specifications: 3m*1/8
Model: DC-550/Chromosorb W NAW DMCS
Application: GB/T 5750.8-2006 Standard Test Method for Drinking Water-Organic Index
The water sample to be tested is placed in a sealed headspace bottle, and after equilibrium at a certain temperature for a certain period of time, the halogenated hydrocarbons in the water escape to the upper space, and reach a dynamic equilibrium in the gas-liquid two-phase. The concentration of the substituted hydrocarbon in the gas phase is proportional to its concentration in the liquid phase. By measuring the concentration of halogenated hydrocarbons in the gas phase, the concentration of halogenated hydrocarbons in the water sample can be calculated.
