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
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
