HACH LANGE Analytical Quality Assurance

Quality Control

The quality of goods and services is crucially important in the current climate. Purchasers and users have come to expect high quality standards from suppliers and manufacturers. This is why the quality of the services and products on offer is checked and documented several times over (e.g. in accordance with ISO 9001). The results of analyses can also be considered as goods and they have to be able to prove their quality so that they can be valued and compared.

ADDISTA

HACH LANGE has created a practical system for operational analysis that unites the individual building blocks of Analytical Quality Assurance. The ADDISTA solutions can be used to carry out the fundamental measures of the Analytical Quality Assurance system. The ADDISTA range includes a standard/spiking solution that is suitable for HACH LANGE cuvette tests, as well as two round robin test solutions. It contains both a standard and a round robin test solution for the field of nutrient process analysis.
