What it means
Identification confirms that each compound is exactly what it claims to be.

Why it matters
Misidentification is one of the most common causes of downstream variability. If the identity isn't correct at the start, no amount of work can fix this.

How it's tested
Identity is confirmed using RP-HPLC with UV detection, a precise analytical method that separates and quantifies components to confirm the expected composition.

Purity analysis is the process of determining the percentage of a sample that consists of the desired target peptide versus impurities, byproducts, or contaminants.

The process of verifying the actual amount present in a vial or container to ensure it matches the labeled quantity. This testing helps confirm accurate dosing, batch consistency, and quality control compliance within manufacturing and packaging processes.

Endotoxin analysis is the testing process used to detect and measure bacterial endotoxin contamination in products. This analysis helps ensure product safety, purity, and quality by verifying that endotoxin levels remain within acceptable limits for research or manufacturing standards.

Sterility analysis is the process of testing for the presence of viable microorganisms such as bacteria or fungi. This testing helps ensure the product is free from microbial contamination and meets quality and safety standards for manufacturing and research use.

Heavy metal analysis is the process of testing products for trace amounts of toxic metals such as lead, arsenic, cadmium, and mercury. This analysis helps ensure product purity, safety, and compliance with quality standards by verifying that heavy metal levels remain within acceptable limits.
