03 / Testing & documentation
A closer look at quality.
Understand the testing behind research materials. Consult the relevant Certificate of Analysis for the methods used and results reported for your batch.
HPLC
High-performance liquid chromatography measures purity, with the reported percentage available on the relevant COA.
Mass spectrometry
Molecular mass measurements help assess whether the tested material is consistent with the intended peptide.
Trace element screening
Heavy metal analysis screens for elements such as lead, mercury, arsenic, and cadmium. Review the report for measured levels and limits.
Bacterial endotoxin testing
Endotoxin testing measures bacterial endotoxins that can affect research. The report documents the method and result.
Microbial screening
Microbial testing assesses contamination in the tested sample. Check the report for the method, scope, and findings.
Peptide quantity
Content analysis measures the amount of peptide in a sample, allowing comparison with the labeled quantity.
