Meridian Bioanalytics runs HPLC purity quantification and mass-spectrometry identity confirmation on research peptides and other compounds. Every result resolves to a public certificate you can check yourself.
From a single vial we confirm what a compound is, how pure it is, and how much of it you actually received — plus the contamination panels that separate a real lab from a self-reported claim.
Reversed-phase UHPLC resolves the main component from synthesis by-products and degradation, reported as area-% with the full chromatogram.
RP-UHPLC · UV/DADMass-spectrometry confirms the molecule is the claimed compound by matching measured mass to the expected molecular weight.
ESI · m/z confirmationNet peptide content per vial — the actual milligrams present versus the label claim, so a 10 mg vial is verified as 10 mg.
mg/vial · net contentBacterial endotoxin screening to USP <85> / Ph. Eur. limits — essential for material intended for sensitive in-vitro work.
EU/mg · USP <85>Elemental impurity screening and residual-solvent / water-content checks for full-panel assessment of unknown sources.
ICP-MS · ppmSterility and bioburden assessment, combined into a single full-vial report alongside identity, purity and content.
bioburden · full panelSamples are received, logged under chain of custody, and run on the same validated instruments every time. Nothing is outsourced and nothing is estimated — every figure on a certificate comes off our own bench.
A certificate of analysis is only worth what you can independently confirm. Each Meridian report carries a unique ID that resolves to a record on our servers — not on a vendor's website. Enter a report number to see what a buyer sees.

every vial in → one verified certificate outTell us the compound, format and assays you need. We confirm price, sample amount and the deadline before you ship.
Send the vial with its batch reference. We provide packaging and customs guidance for EU and international couriers.
Validated UHPLC and LC–MS methods run against traceable reference standards, with redundant instrumentation to avoid delays.
You receive a batch-specific certificate with the chromatogram and a permanent public verification link & QR code.
A full refund and free re-analysis guarantee applies to any report not completed by the agreed deadline. No exceptions, no fine print.
UHPLC and LC–MS systems are mirrored, so routine maintenance never becomes your delay. Day-to-day equipment is held to the same bar as the headline instruments.
Standards sourced from recognised pharmacopoeial directorates and reference institutes, with chemicals carrying their own certificates of analysis.
We are not owned by, affiliated with, or paid based on the result of any peptide or compound vendor. The number on the certificate is the number we measured.
Indicative pricing for routine analyses. Final quotes are confirmed per sample based on matrix and assay combination.
Pricing in EUR · volume & recurring-batch rates on request · crypto and SEPA accepted.
Request a quote and shipping instructions. Most routine reports are completed within 48 hours of sample arrival.
