Peptide Purity and Analytical Testing Methods in Research Settings

Educational overview of standard laboratory techniques commonly referenced in research chemical literature.

High-purity peptides for laboratory use are typically verified using analytical methods such as:

• High-Performance Liquid Chromatography (HPLC) – separates and quantifies peptide components
• Mass Spectrometry (MS) – confirms molecular weight and sequence
• Amino Acid Analysis – verifies composition after hydrolysis

These methods help determine purity percentages (e.g., ≥98–99%) reported on Certificates of Analysis (CoA) provided by suppliers for research purposes. Results are specific to controlled lab testing conditions.
