Insights
From the lab and the loading dock
Analytical methods, quality documentation and industry notes from the Helios Bio Labs team.
Water Content by Karl Fischer Titration in Lyophilized Peptides
A lyophilized peptide is never fully dry. What Karl Fischer titration measures, why coulometric and volumetric methods disagree, and how to read the result.
Residual Solvents in Synthetic Peptides: Reading a Headspace GC Report
A headspace GC report answers one narrow question: which solvents survived synthesis, cleavage and drying. How to read the limits, the blanks and the LOQs.
Storing Lyophilized Research Peptides: Temperature, Moisture and Working Stocks
Lyophilized peptides are stable, not inert. How temperature, moisture, reconstitution and freeze-thaw change a batch, and how to build a stability protocol.
