Frequently Asked Questions
How do I choose the right reference standard for my method?
Match the standard to your analytical technique (HPLC, GC, MS) and method requirements (USP, EP, JP, in-house). Verify traceability, certificate of analysis, expiration date, and storage requirements before use.
What documentation comes with reference materials?
Each reference material includes a certificate of analysis with assigned value, measurement uncertainty, traceability statement, expiration date, and storage conditions. Pharmacopoeia-compliant standards include compendial method references.
What specifications matter most for analytical standards?
Assigned purity and uncertainty, traceability to primary standards, expiration date, storage conditions (often -20°C or 4°C), pack size matching method requirements, and compliance with applicable pharmacopoeia.
How should reference materials be stored after opening?
Most reference materials should be stored at the conditions specified on the certificate (typically -20°C to 4°C), protected from light and moisture. Once opened, use within the period stated by the manufacturer to maintain assigned value validity.
