A laboratory technique for separating mixture components based on differential interactions with a stationary and mobile phase, used extensively in peptide analysis.
Chromatography is a family of analytical and preparative techniques used to separate, identify, and quantify components of a mixture based on differences in their rates of migration through a stationary phase under the influence of a mobile phase. In peptide quality control, several chromatographic methods are employed: High-Performance Liquid Chromatography (HPLC) is the primary method for assessing purity; reversed-phase chromatography separates peptides based on hydrophobicity; size-exclusion chromatography separates by molecular weight; and ion-exchange chromatography separates by charge. When coupled with detection methods like UV absorbance or mass spectrometry, chromatography provides detailed composition profiles. ORYN employs HPLC as a core component of its quality control pipeline, ensuring each batch achieves the >99% purity standard.
