Testing methods, certificate of analysis interpretation, and purity verification.
Residual solvents are governed by ICH Q3C and USP 467 and measured by headspace GC, not by the HPLC assay behind a COA purity figure. A look at the limits, the method, and its documented blind spots.
Elemental impurities in research peptides are trace metals introduced by synthesis catalysts, equipment surfaces, and reagents, and reversed-phase HPLC cannot
Circular dichroism peptide research explained: how CD spectroscopy verifies secondary structure and catches misfolding that HPLC purity and mass data miss.
Trifluoroacetate counterions left on research peptides after HPLC purification can suppress cell proliferation at nanomolar concentrations, a variable invisible to standard purity numbers.
A high HPLC purity percentage on a Certificate of Analysis confirms that a peptide sample contains the correct molecular species
Mass spectrometry is the analytical backbone of peptide identity confirmation and impurity detection in research-grade quality control. This guide covers LC-MS/MS sequence confirmation, MALDI-TOF rapid screening, isotopic pattern analysis, degradation detection, and how to interpret mass spectral data on a Certificate of Analysis.
Peptide impurity profiling is the systematic identification and quantification of unwanted byproducts that arise during peptide synthesis, including truncated sequences,
Accelerated stability testing is a cornerstone of research peptide quality assessment, providing critical data on how peptide compounds degrade under
Endotoxin contamination represents one of the most significant and often overlooked quality control challenges in research peptide science. Bacterial endotoxins,
