Frequently Asked Questions
What does HPLC purity mean?
The percentage of the UV-absorbing signal belonging to the main compound. It does not by itself confirm identity — that's why we pair it with LC-MS.
What is endotoxin testing?
A LAL (Limulus Amebocyte Lysate) assay that detects bacterial endotoxins, reported in EU/mg against a specification limit.
How long does testing take?
Target turnaround is [X] business days from receipt (placeholder).
Can my COA be private?
Yes. Public COAs are listed on the Verify page; private ones are only verifiable with the report ID.
Do results apply to the whole batch?
Results apply only to the sample as received. Conformity testing of multiple vials helps assess batch consistency.
Is testing for human use?
No. All testing is for research use only.
