At Optiq Health Labs, we combine advanced LC-MS technology with precision analytical methods to deliver high-confidence peptide purity testing you can trust. Our laboratory helps researchers and organizations verify peptide composition, detect impurities, and confirm molecular identity through industry-leading analytical testing designed for accuracy, transparency, and consistency.
Purity testing helps determine how much of a sample is actually the intended peptide and how much may consist of unwanted impurities, byproducts, or degradation compounds. Even when a product is labeled as a specific peptide, manufacturing and storage conditions can introduce additional substances that are not part of the desired compound.
Optiq Health Labs, we use advanced Liquid Chromatography–Mass Spectrometry (LC-MS) to evaluate peptide purity with a high level of accuracy. LC-MS separates the components within a sample and confirms their molecular identity, allowing us to determine the percentage of the sample that is the target peptide while identifying other detectable compounds that may be present.
Purity testing is one of the most important quality assessments available, helping verify product consistency, support transparency, and provide confidence that a sample meets its stated specifications.
Purity Testing:
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.

Peptide purity testing is the analytical evaluation of a peptide sample to determine what percentage of the material consists of the intended peptide versus peptide-related impurities or other detectable components.
Optiq Health Labs uses a combination of High Performance Liquid Chromatography (HPLC) and Liquid Chromatography–Mass Spectrometry (LC-MS) for peptide purity analysis and molecular identification.
LC-MS analysis can detect additional detectable compounds within a sample, including impurities, degradation compounds, or manufacturing byproducts.
Yes, but only when purity testing includes mass spectrometry (MS). It can provide identity confirmation by comparing the detected peptide's molecular mass with the expected molecular mass of the target peptide.
This is why testing for purity coupled with LC-MS is important.
Independent purity testing helps verify how much of the sample is the intended peptide versus detectable impurities.
Third-party testing provides an unbiased purity result, helping confirm the supplier's reported purity and identify potential quality concerns.
