HPLC Analysis

High-Performance Liquid Chromatography · Gold Standard

HPLC (High-Performance Liquid Chromatography) is the standard analytical technique for determining peptide purity. It separates the components of a sample and quantifies the percentage of each with sub-percent precision.

FAQ

Frequently Asked Questions About Quality Control

How pure are EXOMA Peptides's peptides?

EXOMA Peptides guarantees ≥99% purity by HPLC across all of its research peptides. If a batch does not meet this standard during analysis, it is automatically rejected and never released for sale.

How often are products analyzed?

Every individual batch is analyzed before release. Analyses from previous batches are never reused. Every vial received comes from a batch with its own analytical characterization.

What is the difference between HPLC and mass spectrometry?

HPLC measures compound purity (what percentage is the desired peptide vs. impurities). Mass spectrometry (MS) confirms molecular identity, verifying that the molecular weight matches the expected structure. Both are complementary and necessary.

Who performs the analyses?

Analyses are performed by certified laboratories with calibrated equipment. Results are verifiable and reproducible under the reported analytical conditions.
