ESI-TOF-MS · ETH Zurich · Switzerland
Independent peptide verification.
Analytical certainty.
Submit any research peptide anonymously. We run high-resolution ESI-TOF mass spectrometry at ETH Zurich and return a verified identity & purity report with a tamper-evident certificate.
Identity
Exact Mass Confirmation
High-resolution ESI-TOF-MS measures the molecular weight of your peptide to sub-ppm accuracy against the expected formula.
Purity
Purity Estimation
LC-MS separation reveals impurities, degradation products, and synthesis residues invisible to simpler methods.
Certificate
Tamper-Evident Certificate
Every result ships with a QR-verifiable certificate ID. Share it publicly or keep it private — your choice.
