SN/T 2994-2011Determination of fluoride, chloride and sulphate in organic chemical products for industrial use. Ion chromatography (English PDF)

SN/T 2994-2011 is the English-translated version of 有机化工产品中氟、氯和硫酸根的测定 离子色谱法.

SN/T 2994-2011 — This standard specifies the ion chromatographic method of water-soluble organic chemical products, fluorine, chlorine and sulfate. This standard applies to alcohols, aldehydes, ketones, nitriles, organic chemical products Determination of fluoride, chloride and sulfate in water solubility.

Principle 2 Samples of fluoride, chloride and sulfate in a polar ionization of water into the aqueous phase, after entering the valve switching means fluorine, chlorine and sulfate anions such enrichment Concentrated in the column, the organic matrix due to the concentrate with water column without adsorption into the waste tube to achieve separation of the organic matrix, adsorbed on the column was concentrated Fluorine, chlorine and sulfate eluted directly into the sample was determined by ion chromatography. Retention time qualitative than quantitative standard method.
