KM KYOTO ELECTRONICSMANUFACTURING CO.，LTD.KVX01513-enLKM KYOTO ELECTRONICSMANUFACTURING CO.，LTD. Application Memo Moisture Determination in Food Additive and Sugars IndustryFood and beverageInstrumentKarl Fischer moisture titratorMeasurement methodVolumetric titration (Direct method)StandardsJIS K0113， ASTM E203， ISO 760 1.Overview Moisture titration with Karl Fischer reagent is the most reliable moisture measurement methodin the world. The procedure is adopted in many official standards as test method specified inISO， ASTM， DIN， BS and JIS. Here in this application， we measure water content in the samples by direct method of KFtitration according to JIS K 0113. Some sample may not dissolve in the solvent， butmeasurement can be performed without problem. 2.Apparatus Main unit Karl Fischer moisture titration volumetric system Electrode Twin platinum electrode 3.Reagents Titrant KEMAQUA titrant TR-3 and TR-5Solvent KEMAQUA solvent SA for sugar 4.
