Laboratory Testing performed by BTLABs

“more than 25 years experience performing pharmaceutical analysis.”

BTLabs, Powered by BioTools

HPLC

High-performance liquid chromatography

Measures peptide purity, potency, and related substances using UV detection at a wavelength suited to the sample.

FTIR

Fourier-transform infrared spectroscopy

Uses a sample’s infrared fingerprint to support identity and composition analysis, screen for excipients, and assess characteristic amide bands associated with protein structure.
