Spectroquant® CombiCheck solutions are ready to use multi-parameter standards for the range of applications of Spectroquant® test system. Each pack contains a standard solution and a spiking solution. Both solutions can be used for quality assurance as they are, without dilution.

The standard solution can be used to confirm the accuracy of the results from the Spectroquant® system as a whole (photometer, reagents, analytical procedure, implementation). The spiking solution can be used to test for sample-dependent effects by measuring the recovery and confirms the suitability of the sample preparation technique.

The maximum number of determinations when using the standard solution depends upon the test system used.
