• Sample Assay: This is the amount of the compound in the vial we tested determined by HPLC analysis.
• Sample Purity: This is purity of the sample, calculated including peaks around the compound that may be
impurities.
• ID by RT: This is an identification test in which the retention time of the sample is compared to the average
retention time of five reference standard injections.
• ID by Spectral: This is an identification test in which the UV spectrum of the sample is compared to the UV
spectrum of the standard.
• System Suitability: This value shows that the HPLC system was running properly throughout your testing. The
%RSD of the standard injections performed before your sample and the standard injection performed after your
sample is calculated to ensure there were no system errors during your run. Although system errors such as leaks,
a line running dry, air bubbles, etc. are rare, it's important that we demonstrate no errors occurred during analysis.
• Coelution Control: NOTE: This value is not purity of the compound - the peak is pure compound as it was
separated out by the HPLC. This value demonstrates that there is no co-elution occurring during analysis. We
receive samples from a multitude of manufacturers and each has their own recipe (stabilizers, solubilizers, fillers,
etc) in their process. This measurement ensures that none of these other components interfere with the analysis.
In short, this number confirms that the method is working properly and only analyzing the target compound.
Important Testing Notice
The analytical results detailed herein pertain solely to the presence of the specified compounds in the samples as
submitted. These results are generated by our independent partner laboratory. It is acknowledged that all prepared
lyophilized peptide products and any other tested material may include stabilizers, solubilizers, fillers, and other
excipients and ingredients, which are not tested for unless explicitly noted in the testing agreement and this Certificate of
Analysis (COA). The results provided do not imply suitability for any specific use or purpose, and testing is limited to the
adherence of our partner laboratory to recognized professional standards during the testing process.
Clients and other users are advised that the responsibility for determining the
applicability of these results for any use rests entirely with them. It is imperative that any users of this information consult
with a physician prior to using any peptide or other compound. Peptides or other compounds sold for "research purposes"
may not be suitable for human use. Any liability for the provided analytical results is confined to the procedural
adherence of our partner laboratory to recognized professional standards during the testing process.
Microbiological analyses are in accordance with USP 71 Sterility (total viable bacteria) using two non-selective broth
media. Results reported are provided as-is and relate only to samples tested. A satisfactory result only indicates that no
contaminating microorganism has been found in the sample examined under the conditions of the test.
