Using advanced LC-MS technology, Optiq Health Labs provides independent peptide identity verification to confirm that your sample matches the expected molecular profile. Our analytical testing delivers accurate, transparent results that help researchers and organizations verify product authenticity with confidence.
Identity verification measures how much peptide is present in a sample—not just whether the peptide is there.
The lab separates the peptide by liquid chromatography, confirms its identity by mass spectrometry, then compares the sample response against a known standard to calculate the total amount of peptide present.
How much does LC-MS peptide purity testing cost and how long does it take?
Purity testing is one of the most important analytical procedures used in peptide quality assessment. Even when a product is labeled as a specific peptide, manufacturing processes, handling conditions, storage environments, and degradation over time can introduce additional compounds that are not part of the intended material.
At Optiq Health Labs, we use advanced Liquid Chromatography–Mass Spectrometry (LC-MS) methods to evaluate peptide purity with a high level of precision and consistency. LC-MS technology separates the individual components within a sample while simultaneously confirming molecular identity through mass analysis.
This process allows our laboratory to:
Liquid Chromatography (LC) separates the individual compounds within a sample. Mass Spectrometry (MS) then identifies and analyzes those compounds by measuring their molecular mass and structure.
We utilize Liquid Chromatography–Mass Spectrometry to separate compounds within the sample and identify the molecular mass of detectable components.
Testing helps determine the relative percentage of the intended peptide compared to other detectable substances present in the sample.
Mass spectrometry helps verify that the detected primary compound aligns with the expected molecular profile of the target peptide.
Analysis may reveal manufacturing impurities, degradation compounds, residual byproducts, or other detectable materials within the sample.

Identity verification testing measures the amount of a specific peptide present within a sample. It verifies that the sample contains the peptide it is claimed to contain.
It will show as confirmed or unconfirmed on the COA.
Optiq Health Labs uses Liquid Chromatography–Mass Spectrometry (LC-MS) to separate sample components, confirm peptide identity, and compare the detected response against a known analytical standard to quantify peptide content.
Peptide products may vary in concentration due to manufacturing conditions, storage, handling, or formulation differences. Identity verification testing helps verify measurable peptide content and supports product consistency evaluation.
Purity testing evaluates how much of a sample consists of the intended peptide versus impurities or degradation compounds.
Identity verification testing measures the quantity of the target peptide present within the sample.
A variety of peptide-based research samples may be evaluated depending on the testing requirements and sample condition.
