Certified test equipment
Quality assurance and quality control regulations, such as ISO 9001, GLP, GMP, and Pharmacopeias, require companies to verify the consistently excellent performance of any spectrophotometer in use. The two most important factors for obtaining precise spectrophotometer data are the photometric accuracy (absorbance accuracy) and wavelength accuracy of the spectrophotometer, which should be tested on a regular basis.
In the Hellma Analytics calibration laboratory, which is accredited to DIN EN ISO 17025, we manufacture certified reference materials based on the regulatory codes issued by NIST (National Institute of Standards and Technology), ASTM (American Society for Testing and Materials) and Pharmacopeias (Ph. Eur., USP). All certified measurement results can be traced back to NIST (photometric accuracy) or to PTB (Physikalisch-Technische Bundesanstalt) (wavelength accuracy) standard reference materials. (Photometric accuracy: NIST SRM® 930e, NIST SRM® 1930. Hellma 666S300; wavelength accuracy: Hellma 667005)
