Starna’s heat-fuse sealing capability helps users to address more safely the requirement to prepare a linear serial dilution in a volatile solvent which is not an easy analytical technique. Heat-fuse sealing also helps with precision because it removes the need for users to fill and measure optical cuvettes from pre-filled ampoules, which can prove a delicate and error-prone activity.

The new CRM is suitable for qualifying photometric linearity HPLC diode array systems and will appeal to pharmaceutical QA laboratories and customer support organizations. The CRM enables Operational Qualification (OQ) and Performance Qualification (PQ) using ‘industry standard’ protocols.

The Starna photometric linearity CRM is supplied with Certification of Validation that details the linearity of the CRM set, produced by measurement on a reference UV-Vis spectrophotometer in the company’s UKAS ISO 17025 and ISO Guide 34 accredited calibration laboratory.
