Batch-to-Batch Consistency in Research Peptides: What Drifts and Why
Two vials carrying the same sequence are rarely identical. What actually drifts between batches in solid-phase synthesis, and how to specify consistency.
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.
