CRM for UV-Visible Spectroscopy​

UV-Visible spectroscopy stands as a pivotal instrumental technique within the realm of analytical chemistry, notably finding paramount utility in the life sciences. Its pervasive application underscores its significance, rendering it subject to stringent regulation by esteemed pharmacopoeias and quality assurance bodies on a global scale. In this context, Starna emerges as a preeminent provider, offering an unparalleled spectrum of Certified Reference Materials (CRMs) meticulously crafted for the precise qualification of UV-Visible Spectrophotometers. Our mission is to empower instrument users with the tools necessary to attain compliance with unwavering confidence.

The judicious selection of reference materials assumes paramount importance, with a preference for those endowed with calibrated values that encompass the precise conditions envisaged for the analysis. While regulatory bodies such as Pharmacopoeias may proffer recommendations concerning specific reference materials, it is essential to recognize that any Certified Reference Material endowed with appropriately certified values possesses the inherent capability to serve as a qualified reference for the attainment of compliance.

Certified Reference Materials is traceable to international primary standards, allowing laboratories to demonstrate evidence of quality control according to ISO/IEC 17025, the universally recognised standard for laboratory accreditation.  Please contact us for further information regarding our Certified Reference Materials and their adherence to exacting standards.

Instrument Qualification Kits


​These kits allow instrument qualification over the stated wavelength and absorbance ranges for compliance with EP 2.2.25 and USP . References are provided to qualify wavelength accuracy, absorbance accuracy and 3-point linearity, stray light and resolution/bandwidth.
