01 / Our expertise

The question shapes the analysis.

Small samples.
Substantial insight.

From molecular identity to what else is present. We help you ask the right questions — and select the analysis that can answer them.

01

Peptide Identity & Purity

Analytical characterization of peptide samples using chromatographic and mass-based analytical data.

Discuss analysis 02

Advanced Peptide LC-MS

Extended peptide characterization for samples requiring deeper mass-based analytical interpretation.

Discuss analysis 03

HGH Content & Purity Analysis

Characterization of human growth hormone samples, covering protein content, chromatographic purity and protein-related impurities.

02 / Our perspective

Evidence first.
Clarity always.

Meet Certa

A result is only useful when you can understand how it was reached.

01

The right question.

Every sample starts with an analytical question. We assess scope and feasibility before any testing is agreed.

02

The appropriate method.

Chromatography, mass spectrometry and complementary techniques. Selected for what your sample needs to establish.

03

The complete picture.

Measured values, methods and interpretation in one structured report. With the limits of the analysis made clear.

03 / The process

Clear at every step.

A considered process.
From start to finish.

One analytical inquiry. An agreed scope. A documented result. Here is how we get there together.
