Inorganic impurities such as metals and noncombustible materials are typically evaluated using compendial procedures. 908.534.4445, david.browne@intertek.com. Inorganic impurities. Identification of impurities. As a rule, an International Standard for a material of natural origin is discontinued once the substance responsible for its characteristic activity has been isolated, identified, and prepared in such form that it can be completely characterized by chemical and physical means. Wherever possible, therefore, compendial methods should be used to qualify reference standards.

On the 23rd February, AXIO, Dr Ehrenstorfer and Digamma Consultancy will come together to answer your questions on cannabis testing. If the amount of residual solvents present affects the purity, however, they should be evaluated at each requalification interval. This timeframe will also help to avoid delays in testing for subsequent programs due to an expired reference standard. An additional specific test procedure may be required if the USP procedure is not suitable for the reference standard being evaluated, or if the solvents used during synthesis are not included in USP <467>. The US Pharmacopeia (USP) defines reference-standard materials as "highly characterized specimens of drug substances, excipients, reportable impurities, degradation products, compendial reagents, and performance calibrators" (2).

USP, however, labels its reference standards (assay reference standards to the nearest 0.1% and impurity reference standards to the nearest percent). Impurities that arise from raw materials, synthesis, purification, and storage require careful consideration because they may not produce detector responses that are related to the reference-standard material. In the list that follows, chemical names are given for many substances (e.g., related compounds) that are not, L Valentin Feyns, Director, Reference Standards Evaluation. Reference-standard materials can be broadly categorized as such: The level of characterization depends on the intended use of the reference standard.

For example, if the intended storage condition is 28 C then the reference standard should also be stored at 20 C as a contingency. If analysis shows an impurity at 0.05% and the relative response factor of the impurity is half of the standard (i.e., the amount of impurity present shows a 50% detector response compared with the equivalent amount of standard), then there could be 0.1% of actual impurity.
