Description

For few parameters such as nitrite, which are subject to a quick conversion, freshly prepared control standards of stock solutions versus the multi-parameter standard checks are mandatory. Stock solutions are also more cost-effective than the already confectioned CombiChecks™. With stock solutions, the correct dilution must be self-calculated and conducted. The use of standards is supported via AQA functions in the photoLab™ photometers.
