Photometry multi-parameter standards
Multi-parameter standards for error-free AQA in routine and water analysis by premade concentration matching the test kit and spiking
- Matching concentration to test kit
- No calculation errors
- Stocking solution
CombiChecks® are multi-parameter standards and supply the correct volume of ready-made concentration in the center of the measuring range: Everything is set matching to the respective test kits. Contrary to normal standard solutions, this does not require the dilution with calculations of the concentration or pipetting volumes and thus prevents inadvertent volume and pipetting errors. Another benefit is the premade spiking solutions for the examination of matrix effects or interfering ions.
The lot certificates of the CombiChecks® contain data for the concentration, confidence range and lot values. The concentration and confidence range can be entered into the photoLab® photometers via a menu for the AQA documentation.
