GB/T 8570.5-2010 "Determination of Liquid Anhydrous Ammonia—Part 5: Water Content—Karl Fischer Method" specifies the method for determining trace water in liquid anhydrous ammonia using the Karl Fischer method. This method involves vaporizing the ammonia sample and introducing the water vapor into a Karl Fischer titration cell using a dry carrier gas for reaction and coulometric determination, thereby calculating the water content. It is applicable to the quality control of liquid anhydrous ammonia products.
