Peptide Analysis

HPLC analysis RP-HPLC (reversed phase) SEC-HPLC (size exclusion) IE-HPLC (ion exchange) method develpment and validation for Non-GMP and GMP projects. Mass Spectrometric analysis ESI-MS full scan LC-MS LC-MS-MS Amino Acid Analysis Proteins/peptides are hydrolyzed using HCl. The released amino acid residues are analyzed on a reversed phase HPLC after pre-column derivatization.
