RESEARCH LIBRARY
Independent educational resources covering analytical chemistry, peptide characterisation and research compound information.
The library is intended to explain scientific and analytical terminology clearly, including how different analytical techniques and reported measurements should be interpreted.
Peptide Purity vs Identity: What’s the Difference?
Why chromatographic purity, molecular identity and quantity are separate analytical concepts, and how different techniques provide different information.
Read Article →How to Read a Peptide Certificate of Analysis (COA)
A practical guide to understanding analytical reports, including sample identification, HPLC results, chromatograms, mass spectrometry and supporting data.
Read Article →What Are Lyophilised Peptides? A Research Guide
An introduction to lyophilisation, how freeze-drying works, why it is used for peptide materials, and why storage requirements remain product-specific.
Read Article →Peptide Molecular Weight, Formula and Sequence Explained
A guide to three fundamental pieces of peptide information: amino-acid sequence, molecular formula and molecular mass, and how each describes a different aspect of a peptide.
Read Article →HPLC vs Mass Spectrometry: Understanding the Difference
A guide to how HPLC and mass spectrometry provide different analytical information, why the techniques complement one another, and how they can be combined as LC-MS.
