Umwelt-Prüfkits

CombiCheck solutions are ready-to-use multi-parameter standards, Each package contains a standard solution and an addition solution. Both solutions can be used directly without dilution for quality assurance.


  • The standard solution is used to check the accuracy of the results for the complete system: procedure - analytical method - reagents - photometer
  • The addition solution is used to check sample-dependent influences by measuring the recovery rate and to determine the most suitable sample preparation method


The maximum number of determinations which can be made with a CombiCheck standard solution depends on the test set used. With the addition solution 280 determinations are always possible.


Parameters can be checked with their concentrations as follows:
Ammonium: 4,00 mg/L NH₄-N
Chloride: 25,0 mg/L Cl
COD: 80 mg/L COD
Nitrate: 2,5 mg/L NO₃-N
Phosphate: 0,80 mg/L PO₄-P
Sulphate: 100 mg/L SO₄
