What is stated on the certificate
Content and purity are assigned per lot and stated on the certificate of analysis issued for the batch you receive — they are not a catalogue-level figure. The certificate records the tests performed, the specification applied and the result obtained for that lot.
| Field | Basis |
|---|---|
| Identity | Spectroscopic and chromatographic methods appropriate to the material |
| Purity | Chromatographic purity, area normalisation unless stated otherwise |
| Assay / content | Mass balance, corrected for the stated volatiles and residue |
| Catalogue and batch numbers | RS-G012032 / batch number on the certificate |
| Retest date | Printed on the certificate for the lot supplied |
Frequently asked
What documentation is supplied with this lot?
A certificate of analysis (COA) is issued for the lot you receive. It records the catalogue number
RS-G012032 and the batch number, the tests performed, the
specification applied and the result obtained. A safety data sheet is supplied with the shipment.
Is the assigned value given on an “as is” basis?
Content and purity are stated per lot on the certificate of analysis, on an “as is” basis unless the certificate says otherwise. The analytical basis for the assigned value is stated on the certificate.
How should this material be stored?
Storage and shipping conditions are stated on the certificate of analysis for the lot you receive. Re-test before use beyond the retest date printed on the certificate.
Do you supply pack sizes other than those listed?
Pack sizes are confirmed with the quotation. Quantities beyond the standard pack sizes can be quoted — send the quantity you need with your enquiry.
