Endotoxin testing helps identify bacterial contamination that may not be detected through standard peptide analysis. Using advanced ELISA-based testing, Optiq Health Labs screens peptide samples for bacterial endotoxins to support product quality, transparency, and confidence, especially for injectable formulations.
Optiq Health Labs, we perform endotoxin testing to help identify bacterial endotoxin contamination and provide a more complete evaluation of peptide quality. This analysis is particularly important for products intended for injection, where even small amounts of endotoxins may lead to adverse reactions.
At Optiq Health Labs, we use an advanced ELISA-based endotoxin testing system to detect and measure bacterial endotoxins in peptide samples. This testing helps identify contamination that may otherwise go unnoticed and provides an additional layer of confidence for products intended for injection.
For injectable peptide products, endotoxin testing is essential because what cannot be seen can still matter.
Peptides are often most stable within a specific pH range. Solutions that are excessively acidic or alkaline may contribute to peptide degradation, reduced stability, or increased injection-site irritation. pH testing provides valuable insight into formulation quality and helps ensure greater consistency from batch to batch.
If endotoxins are introduced into the body, they may trigger unwanted inflammatory responses such as fever, chills, irritation, or injection-site reactions. Endotoxin testing helps verify that a product has been properly manufactured, handled, and screened for bacterial contamination.
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.

Endotoxins are bacterial toxins that can contaminate peptide products during manufacturing, packaging, or handling.
They are not visible and cannot be identified through standard purity or identity testing alone.
Injectable products may introduce contaminants directly into the body. Even small amounts of endotoxins may contribute to inflammatory or adverse reactions, making screening especially important.
Yes. Purity testing evaluates the composition of a peptide sample, while endotoxin testing specifically screens for bacterial toxins.
A product may appear pure while still containing endotoxin contamination.
Optiq Health Labs uses an advanced ELISA-based endotoxin testing system to detect and measure bacterial endotoxins in peptide samples.
