Peptide Impurity Profiles: Deletion and Truncation
A peptide impurity profile maps deletion sequences, truncated chains, and chemical modifications per lot. Learn how HPLC and MS build a full COA.
Peptide Purity vs Potency: Why They Differ
Peptide purity is the HPLC-confirmed percent of target compound per lot. Potency is the bioassay-measured biological response. Learn what a COA shows.
How Peptide Identity Is Confirmed in the Lab
Peptide identity confirmation uses mass spectrometry and HPLC to verify molecular weight and purity of every research lot. Learn how COA data is generated.
Batch-to-Batch Variance in Peptide Manufacturing
Batch-to-batch peptide variance is the measured purity difference between production runs. HPLC, mass spec, and lot-specific COAs verify each batch.
How to Spot a Fake Peptide COA: Lab Verification Guide
Fake peptide COAs show round purity numbers, missing lab details, and reused chromatograms. Learn to verify any COA using ISO accreditation checks.
Underdosed Peptides: How Concentration Is Verified
Underdosed peptides have high purity but low actual concentration. Net peptide weight on the COA verifies the true active amount per vial.
How to Read an HPLC Chromatogram for Peptides
An HPLC chromatogram plots retention time vs detector response. The main peak area percent gives purity. Learn to read peptide COA chromatograms.
