在一定温度下,空气中含有一定量的水分。如果能够利用简单的式子计算出或者在表上查出某一温度下1ml空气中的水含量(mg/ml),就可以将该温度下的空气送入色谱柱,经分离后得到水的峰高(或面积)。从而计算出单位峰高(或面积)所代表的水含量(mg)。以此为基准可以方便地计算出液体或气体样品中的水含量,可以省去配制标准水样的繁琐工作。为此我们推导出了空气中的水含量计算式。并利用此计算式和空气的相对湿度表进而计算、编制出了空气中的水含量表(mg/ml)。这样 At a certain temperature, the air contains a certain amount of water. If a simple equation can be used to calculate the water content (mg / ml) in 1 ml of air at a given temperature on the table, the air at that temperature can be fed to the column and separated to give water Peak height (or area). The water content (mg) represented by the unit peak height (or area) is thus calculated. Based on this, the water content in liquid or gas samples can be easily calculated, which can save the cumbersome work of preparing standard water samples. To this end, we deduced the equation of water content in the air. And use this formula and air relative humidity meter and then calculate the preparation of the air in the water content table (mg / ml). such
