Photometry Standard Solutions

Standard solutions as stock solution to dilute for error-free analytical quality assurance (AQA) in routine and water analysis

High quality with lot certificate
Cost-effective as stock solution
Programmable AQA

Описание

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.

Standard solutions with limited stability, to be freshly prepared at regular intervals:

Free chlorine
Bound chlorine
Formaldehyde
Hydrazine
Hydrogen peroxide
Hydrogen sulfide
Phenol
Silicon
Sulfide
Sulfite
Anionic surfactants
