Analysis scoped to your sample.

Mass-spectrometric and chromatographic methods confirm exactly what a sample is — a peptide sequence, small molecule or other analyte — matched against a reference standard where one exists, or characterized from first principles where none does. The finding is issued as an identity result on your Certificate of Analysis, verifiable online at any time.

Quantitative analysis determines how much of a declared compound a sample actually contains, run on calibrated instruments against a defined method and, where applicable, a reference standard. Assay is reported as its own result, separate from purity — the two answer different analytical questions — alongside the method and acceptance criteria applied.

Chromatographic separation resolves a compound from related substances, degradation products and process impurities, each identified and quantified against a reporting threshold. Purity is reported as its own result on the certificate, distinct from — and never a substitute for — a quantitative assay.

Multi-component samples — peptide blends and other formulated mixtures — are approached component by component rather than as a single unidentified material. Each declared constituent is identified and quantified individually, compared against the declared composition, and reported together on a single certificate.

Samples are tested against a reference batch, a prior result or a client specification to establish whether they are consistent — supporting incoming-material checks, supplier verification and routine batch-to-batch monitoring for clients running recurring testing programs.

Where a compound has no existing monograph or falls outside our published coverage, our analysts review the substance, any available reference information and the analytical objective, then scope an appropriate testing approach — adapting an existing method or developing one around the sample itself.
