Secondary standards for calibrating spectrophotometers

Secondary standards for calibrating spectrophotometers
To maintain constant good measurement results, a regular review of the accuracy of the spectrophotometer is required. With the use of certified reference materials from Hellma Analytics, you make sure that your equipment qualifications meet the requirements of the pharmacopoeias and fulfill your internal quality requirements, at the same time you reach the international comparability of your measurement results. The certified reference materials (calibration standards) of the DIN EN ISO 17025 accredited Hellma Analytics calibration laboratory are traceable to the primary standards of NIST (National Institute of Standards and Technology) and meet the requirements of the major pharmacopoeias (e.g. EP, DAB, USP).
Your benefits:
-High quality of the measurement results
-International comparability of measurement results
-Meeting the requirements of the major pharmacopoeias (EP, DAB, USP)
-Results traceable to NIST primary standards
-30 years warranty on the reference materials
Scope of delivery:
