标准范围

规定方法的原理是将测量体积的气体通过含有相对较小体积的吸收性溶液的电池。气体中的水由吸收剂溶液萃取，然后用卡尔·费歇尔试剂滴定。选择电池和吸收剂溶液的设计，以确保在必要的高流速下有效收集水。适用于浓度在5 mg/cm^3和5000 mg/cm^3之间的水。

The principle of the method specified is passing a measured volume of gas through a cell containing a relatively small volume of absorbent solution. Water in the gas is extracted by the absorbent solution and subsequently titrated with Karl Fischer reagent. The design of the cell and the absorbent solution are chosen so as to ensure efficient collection of the water at the high flowrates necessary. Is applicable to water concentrations between 5 mg/cm^3 and 5000 mg/cm^3.
