설명

일반 설명

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

애플리케이션

This pharmaceutical secondary standard can also be used as follows:

• Quantitative analysis of four short-chain fatty acids and lactic acids by high-performance liquid chromatography (HPLC) combined with a UV detector from the supernatant of bacterial cultures
• Spectrophotometric determination of lactic acid at 390 nm in biological cultural and dairy products

분석 메모

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
