Answer each question against the certificate in front of you. The tool scores what the document establishes, names what it leaves open, and writes the questions to send back to the supplier. Nothing is uploaded and nothing is stored: it runs entirely in your browser.
There are two separate questions to ask about any certificate. Is the document what it claims to be, and is it about the vial you are being sold? A certificate can be entirely genuine and still cover a batch produced eighteen months ago. The checks below cover both.
Whether the file in front of you is a certificate as issued, or a picture of one.
The check almost nobody performs, and the one that catches substitution rather than forgery.
A result is only readable next to the method that produced it and the trace it came from.
A certificate can be entirely genuine and still be about material you will never receive.
This tool evaluates documentation only. It makes no assessment of any material, gives no usage, dosage or handling guidance, and its output is not a verification of any supplier or product. A purity figure belongs to the single batch it was measured on. Read our compliance position.
Ask two separate questions. Is the document what it claims to be, and is it about the vial you are being sold? For the first, contact the laboratory named on the certificate and ask it to confirm the report, using contact details you find on the laboratory's own site rather than the ones printed on the document. For the second, check that the batch reference on the certificate matches the batch reference on the vial, character for character.
The compound named in full, a unique batch or lot reference, the vial size or fill weight, an identity result with the method that produced it, a purity result with the method named, the test date, the laboratory's identity and contact details, and the chromatogram rather than the summary figures alone.
It is a marketing decision rather than a measurement. Purity is determined per batch by one method on one date, so a single figure applied to an entire catalogue cannot have come from testing every batch in it.
No. It scores a document against the fields a certificate should carry and tells you what is missing. It makes no assessment of any material and gives no usage or handling guidance. The only check that confirms a certificate is contacting the issuing laboratory yourself.
Scoring weights the 18 checks by how much the certificate depends on each, out of 41 points in total.
