FAQ
What is a Certificate of Analysis (COA)?
A COA is a laboratory report documenting analytical results for a specific submitted sample. Depending on the testing performed, it may include identity, chromatographic purity, net peptide content, and other analytical information.
What does identity testing confirm?
Identity testing helps determine whether the primary compound detected in a sample matches the expected substance. It does not by itself confirm purity, quantity, sterility, or safety.
Is purity the same as net peptide content?
No. Chromatographic purity describes how much of the detected material corresponds to the target compound, while net peptide content measures how much target peptide was actually found in the submitted sample.
What does HPLC tell you?
High-performance liquid chromatography separates components within a sample and can help assess chromatographic purity and related impurities. The meaning of the result depends on the analytical method used.
What does LC-MS/MS tell you?
LC-MS/MS combines liquid chromatography with mass spectrometry to provide highly specific analytical information about compounds present in a sample and can support identity and quantitative testing.
Why does batch-specific testing matter?
A laboratory report only represents the sample that was actually tested. Results from one vial, lot, or batch should not automatically be assumed to represent another.
What can a COA not tell you?
A COA does not automatically establish safety, effectiveness, sterility, suitability for human use, or the quality of unrelated batches. It should be interpreted within the scope of the testing performed.
Does Eleva sell research peptides?
Eleva is currently focused on analytical testing education, COA interpretation, research documentation, and independent testing resources rather than operating a public peptide storefront.
