Residual Solvent Reports
Every lot is screened by GC-MS for residual process solvents, plus trifluoroacetic acid (TFA) by ion chromatography, before release. Browse and download the residual solvent report for any peptide in our catalog.

Residual solvent reports on file
Peptides are built and purified with organic solvents, so every batch is screened before release to show how little of those solvents is left behind. The screen is run by gas chromatography (GC-MS), with trifluoroacetic acid measured separately by ion chromatography, and the limits referenced against USP <467>. Each report names the batch it belongs to, lists the solvents looked for, and gives each one either a measured amount in parts per million or a "not detected" result. To read one, match the batch reference printed on your vial to the batch reference at the top of the report, then read down the solvent list: every line should sit under its stated limit. The table below lists every product with a residual solvent report on file. Third-party testing is performed by ISO/IEC 17025-accredited laboratories — Vanguard Laboratory (A2LA cert. 6377.01.01) and Ethos Analytics (cert. 117798). All products and documents shown here are supplied for laboratory research use only.
