With the new ValidCheck Standard solutions, the user has ready-to-use solutions for this task. The exactly adjusted concentrations are adapted to the respective application. The dilution is omitted. With the ValidCheck Multistandards, the user can immediately check all the important analytical methods of an application with one product: anions and metals in the drinking water analysis or the analysis of the wastewater treatment and process. In addition, the multistandards contain a top-up solution with which the influences of the sample matrix on the analysis result can be reliably determined.
