GB/T 23977-2009 《Dyestuffs - Determination of content of salt - Conductance method》 Related products

This standard specifies the method for determining the salt content in dyestuff by conductivity method, which is applicable to the determination of the salt content of dyestuff in sodium chloride (NaCl). This method calculates the salt content of the sample by measuring the conductivity of the dyestuff solution. The standard describes in detail the preparation of reagents, the preparation of standard Linear dispersion and the use of the Conductivity Meter. This method provides a reliable means of detection for dyestuff production and quality control, helping to ensure that the product meets relevant requirements.
