Algemene informatie

Iodine Value Determination

The iodine value is a measure of the unsaturated fatty acids in glycerides. The more olefinic double bonds there are in the fat, the higher the iodine value.


Peroxide Value Determination

The peroxide value of a substance denotes how much peroxide it contains. In a mixture of glacial acetic acid and chloroform, the peroxide oxidises the iodide into elementary iodine. The resulting quantity of iodine is then back-titrated using a thiosulphate solution (where a starch solution is used as the indicator). The blank solution tested in parallel is used to calculate the results.


Volumetric Standard Solutions

A volumetric standard solution is a solution containing a precisely known concentration of a substance. The concentration of a volumetric standard solution is determined using a primary standard, which is accurately weighed and dissolved to make a specific volume. Volumetric standard solutions are made using reagent-grade (p.a.) substances as source materials.


Volumetric Standard Solutions, ready-to-use

The advantages of this over making them yourself are:

  • Manufactured and tested using modern manufacturing and analytical methods
  • Ready-to-use solutions
  • High accuracy for precise analyses
  • Application of NIST-certified reference substances for checking
  • Connection to standard titrators is possible
