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. Reference materials from Hellma Analytics help you with this task and create the basis for safe and reliable measurement results.

With regular recalibration of your Hellma Analytics calibration standards in the Hellma Analytics calibration laboratory, you receive a 30-year manufacturer's warranty.

All details on recalibration can be found here.

In the Hellma Analytics calibration laboratory, which is accredited* to DIN EN ISO 17025, we manufacture UV/Vis 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 reference materials provide safe and easy verification of UV/Vis spectrophotometers with the following parameters:

• Wavelength accuracy
• Photometric accuracy
• Photometric linearity
• Limit of Stray light
• Spectral resolution
