Mission Hills, California
HPLC-UV/MS + QTOF-MS
Mission Hills, California
Send sealed vials. We photograph them as received, give them a lab number, run them on our own instruments, and sign the certificate — numbered and permanent, whatever it says. Whether it goes on the public register is your election: stated on the order, confirmed once you have seen the result, and one-way once it is made. You pay for the analysis. You do not buy the result.
Panel 01
Purity
Area normalisation across the whole chromatogram, with the largest single impurity and its relative retention time reported beside it.
HPLC-UV · 214 nm
Panel 02
Identity
Measured mass against a reference standard — observed m/z, charge state, and the mass error in ppm, not a yes or a no.
QTOF-MS · ESI+ · direct infusion
Panel 03
Quantity & label
Recovered mass per vial against the label claim, with Karl Fischer water content so the shortfall can be read for what it is.
Gravimetric · KF titration
What to send
- Sealed vials from the lot, in the container they shipped in. How many depends on the tests you pick — each line in the form says what it ships as.
- The label claim exactly as printed — compound, mass per vial, lot number.
- The name the certificate should carry as commissioning party. It is printed on the record and cannot be changed afterward.
- After payment you’ll print a slip with your order number — it goes in the box, and the number goes on two sides of it.
- Nothing else. No formulation, no customer list, no explanation of what the result ought to be.

Nothing we issue is a certification mark. A certificate reports what was measured on the material received, and nothing beyond it — not sterility, not suitability for human or veterinary use, and not the rest of the lot; results are for research use only. Example records shown on the register are specimen — fictitious.
