What is HPLC?
HPLC (High-Performance Liquid Chromatography) is the standard method for quantitative analysis. The percentage of the main compound is calculated from peak areas in the chromatogram.
How to read a certificate
- Batch number — identifies the production lot
- Purity percentage — e.g. ≥98.5%
- Method — typically HPLC-UV or HPLC-MS
- Performing laboratory — independent accredited facility
Independent laboratories
peptiq uses laboratories accredited under PN-EN ISO/IEC 17025. Every batch is analyzed before release, and the HPLC certificate is available on the product page.
