Test solutions for the determination of photometric accuracy

NANOCONTROL NANOCHECK is a secondary standard for the control of inspection, measuring and test equipment in accordance to ISO 9001 and ISO 14001. The test solutions have been checked in a reference photometer monitored with primary standards (NIST-Standards). The results are documented. With only 2 stable colour solutions the wavelength accuracy and the linearity of the absorbance measurement can be checked.
NANOCONTROL NANOCHECK fullfils the requirements of analytical quality control mentioned in the DWA-advisory leaflet A 704 (Operational Methods for the Self-Monitoring of Wastewater Systems).
