HPLC chromatogram

05101520Retention time (min)
Chromatogram as published by Accumark Labs for report 7ZGT-L9PM. Purity on this certificate is the lab's figure; it excludes the unretained solvent peak near the start of the run.

HPLC testing methodology

High-Performance Liquid Chromatography (HPLC) is the standard analytical technique used to verify peptide purity. Peptide labs typically run reverse-phase HPLC with UV detection. The chromatogram displays retention time on the x-axis and UV absorbance on the y-axis. The area under each peak corresponds to compound quantity. Purity is calculated as the target peak area divided by total peak area, expressed as a percentage. A purity of 98% or above is the usual research-grade threshold.

Storage & handling

Research peptides should be stored lyophilized (freeze-dried) at -20°C or below until ready for use. Avoid repeated freeze-thaw cycles. Upon reconstitution, store at 4°C and use within 30 days. Keep away from direct light and moisture. All handling should be performed under sterile research conditions by qualified personnel following applicable laboratory safety protocols.

Intended use

Thymosin Alpha-1 is supplied for laboratory research purposes only. Not intended for human or veterinary use, diagnostic procedures, or clinical applications.
