Every lot is analyzed by an independent laboratory before release. The certificate covering the lot you receive is included with your order.
What the certificate reports
Each report identifies the lot, the analytical method, the result, and the date of analysis. Identity and purity are determined by reversed-phase high-performance liquid chromatography (RP-HPLC) and mass spectrometry against a reference standard.
Who performs the analysis
Analysis is performed by a third-party laboratory with no ownership interest in this business.
Requesting a certificate
The certificate for your lot is supplied with the order it covers. To request the certificate for a specific lot before ordering, or a replacement copy of one already supplied, write to support@hmdscientific.com with the product name and the lot number.
