Standard Test Method for Total Water in Liquid Butane by Liquefied Gas Sampler and Coulometric Karl Fischer Titration
More info
1.1 This test method describes the use of a specialized liquefied gas sampler coupled to a coulometric Karl Fischer (KF) titrator for the determination of water in liquid butane with water concentrations from 1 mg/kg to 100 mg/kg.
Note 1: Other liquefied petroleum gases described in Specification D1835 including propane, propene (propylene), butylenes and mixtures of these materials and other light hydrocarbons, and dimethyl ether described in Specification D7901, can be analyzed by this method but the precision has not been studied and therefore the stated precision has not been validated for these materials.
