GB/T 23978-2009 For the determination of chloride ion content in liquid dyestuff, Ion chromatography is used. The standard describes the determination principle, specifies the equipment and reagent requirements, and details the pretreatment of liquid dyestuff samples, such as diluting, filtrating and other steps, as well as the operation flow of Ion Chromatography, including parameter setting, calibrated Linear dispersion drawing and sample determination. With this standard, the chloride ion content in liquid dyestuff can be accurately determined, providing key data for dyestuff quality control, helping to improve product quality, and promoting the standardization of impurity detection in the dyestuff industry.
