Peptide Purity
By Peptide Information
At NovaraPeptides.com, we believe that knowledge is power — especially when it comes to science. Our peptides are offered exclusively for in-vitro research purposes, giving scientists reliable tools to explore breakthroughs in medicine, biology, and biotechnology.
Important Notice: Our peptides are not approved for human or animal use, nor are they intended to diagnose, treat, or cure any disease. They are strictly for laboratory research and educational applications.
How is Peptide Purity Achieved and Verified?
At NovaraPeptides.com, we know that purity is the foundation of reliable research. That’s why every peptide we produce exceeds 99% purity — giving scientists confidence that their results are accurate and reproducible.
We use advanced solid-phase and solution-phase synthesis technologies to precisely create each peptide sequence while minimizing unwanted byproducts. After synthesis, every batch is put through rigorous quality control that includes:
High-Performance Liquid Chromatography (HPLC): Separates and measures each component to confirm exceptional purity.
Mass Spectrometry (MS): Confirms the exact molecular weight and verifies the peptide’s identity.
This combination of innovation, precision manufacturing, and thorough testing ensures you receive peptides of the highest quality, every time.
HPLC and Mass Spectrometry
High-Performance Liquid Chromatography (HPLC) is one of the most trusted scientific methods for separating, identifying, and precisely measuring the components of a mixture. This advanced technique ensures that every peptide we produce meets the highest purity standards.
Mass Spectrometry (MS) takes verification a step further by confirming the exact molecular weight and identity of each peptide. It works by ionizing the sample, sorting the ions based on their mass-to-charge ratio, and generating a unique “fingerprint” that proves the peptide’s authenticity.
At NovaraPeptides.com, we don’t just test once — we test at every stage of the production process. This rigorous, step-by-step approach guarantees that every peptide is exactly what you ordered, with the purity and accuracy required for reliable research results.
What is the Recommended Peptide Purity Level?
At NovaraPeptides.com, we provide peptides with >99% purity — the gold standard for research and development. This ensures maximum accuracy and reliability for your experiments.
In general, the higher the purity, the better the results. For applications such as in vitro studies, preclinical research, and clinical trials, extremely high purity (greater than 98%) is essential to avoid skewed data or unwanted variables.
For some less sensitive applications, slightly lower purity levels may still be acceptable — but when precision matters, researchers around the world trust peptides that exceed 99% purity. Our rigorous testing guarantees that every batch meets or exceeds this level, so you can focus on discovery with confidence.
