HPLC purity 99.102%: in the lab's chromatogram, 99.102% of the detected peak area belongs to the KPV Peptide peak and the remaining 0.898% to other components the method detected.
Janoshik Analytical printed no purity specification or pass/fail verdict on this report; the figure is a measurement only.
Measured content of KPV: the amount Janoshik Analytical quantified in the vial it received (11.21 mg). It is a measurement of this sample, not a label figure.
This report carries no identity result: Janoshik Analytical reports measured content and purity only.
Mass spectrometry is not reported on this certificate; the molecular weight in the compound identity section is PubChem reference data, not a measurement of this lot.
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.
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.
KPV Peptide is supplied for laboratory research purposes only. Not intended for human or veterinary use, diagnostic procedures, or clinical applications.
Reference identity data for KPV Peptide, compiled by Peptide Hackers from PubChem — not part of the lab's certificate above, which reports only what the lab measured in this lot.
