The accuracy of an analytical measurement is defined as the closeness of agreement between a test or measurement result and the true value. It usually requires calibration of the analytical method with a known standard. This is often done with standards of several concentrations to make a calibration or working curve.
The highest degree of confidence is achieved with Certified Reference Materials (CRMs), which are characterized by a metrologically valid procedure for one or more specified properties, accompanied by a certificate that provides the value of the specified property, its associated uncertainty, and a statement of metrological traceability, according to the definition stated in ISO Guide 30.
Cifga is the unique lab in the world with ISO 17034 accreditation as reference materials producer in marine biotoxins scope!
Custom concentrations, mixed-toxin formulations and contract purification are handled directly by our production team.
ISO 17034 is the international standard governing reference material producers. Accreditation requires an independent technical audit by an external accreditation body. It is not a self-declaration. CIFGA is a reference materials producer accredited by ENAC (Nº 2/PMR003) for a defined scope of marine biotoxins.
In practice, every CRM in the accredited listing carries a certified value traceable to SI units, with certified value determined by NMR and measurement uncertainty supported by homogeneity and stability studies using HPLC-MS/MS. For laboratories operating under ISO 17025, using a CRM from an accredited producer is the most auditable approach available.
Produced from natural biological sources using biotechnological processes.
Primary production — no redistribution of third-party materials.
Determined in-house, traceable to SI units.
Measurement uncertainty supported by HPLC-MS/MS, UV and fluorescence studies.
Certified value and uncertainty, defensible under ISO 17025 audit.
CIFGA supplies laboratories in over 40 countries. Shipping from Lugo means intra-EU deliveries carry no customs complications and arrive faster than equivalent shipments from North American suppliers, which is relevant for the significant volume of shellfish monitoring conducted under EU regulatory frameworks.
Custom requirements, including specific concentrations, mixed-toxin formulations, and contract purification, are handled through our tailored services, with technical support provided directly by the production and characterisation team.
