Calibration laboratory has Ukas accreditation for all wavelength and absorbance scale procedures associated with filter and sealed cell materials
All laboratories seeking to comply with GLP, ISO 9001 and similar quality standards must demonstrate 'evidence of control' in any audit of their procedures.
Certified reference materials provide one of the major sources of this evidence.
Ultra-violet and visible spectrophotometry is one of the most widely used measurement techniques, and a wide variety of standards is available for instrument qualification, ranging from glass filters to sealed-in-cell solutions.
Many laboratories have purchased these materials from various vendors and at different times leading to the logistical nightmare of ensuring that they are always in calibration, and that the right set is sent to the appropriate vendor for recalibration The Starna accredited re-calibration (Star) service offers a single route whereby all these different sets of materials can be re-certified, traceable to the appropriate National Institute of Standards and Technology (NIST) primary SRM materials, and in an accredited environment.
The Starna calibration laboratory has United Kingdom Accreditation Service (Ukas) accreditation to ISO/IEC 17025 for all wavelength and absorbance scale procedures associated with filter and 'sealed cell' materials. This gives the assurance of a truly established traceability path, independently assessed by third party quality organisations.
