Reference materials are only considered to be certified if they have been issued with a DAkkS calibration certificate and bear a calibration mark. Hellma Analytics runs the only calibration laboratory in Germany, which is accredited for the measurement of UV / Vis reference materials by DAkkS according to DIN EN ISO/IEC 17025. The accreditation is valid only for the scope listed in the annex of the accreditation certificate D-K-18752-01-00. Whether glass filter or liquid filter - certified reference materials from Hellma ensure reliable measurement results and guarantee highest process transparency.
Spectrophotometers in instrumental analytics have to be checked on a regular basis! Quality assurance and control regulations, such as B. ISO 9001, GLP, GMP and the pharmacopoeias, require a regulated performance verification of the UV / Vis spectrophotometers in use. Certified reference materials from Hellma Analytics help you with this task and create the basis for safe and reliable measurement results.
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 Pharmacopoeias (Ph. Eur., DAB, USP). With the utmost care in selecting materials, manufacturing under controlled conditions, and traceability to NIST standards, Hellma certified reference materials provide safe and easy verification of UV/Vis spectrophotometers with the following parameters:
