Certified Reference Standards

Stay Current With Grace Davison Discovery Sciences' Certified Reference Standard Offering

As a supplier of drug and metabolite standards for over 30 years, we are continually updating our drug standard offering to keep up with the demand of new analyses performed by toxicological and forensics laboratories. Our drug standards are available in three convenient formats. 

• Quik-Check™ solutions are packaged in ready to use ampoules at stated concentrations. Quik-Check™ Solutions are DEA exempt and do not require a DEA license for purchase.  
• Dilute ‘N Shoot™ Standards are pre-weighed standards supplied in a 15mL capacity bottle. This option allows the sample to be diluted in any appropriate solvent to any desired concentration down to 0.7ug/uL.  
• Neat standards offer the most flexibility for use, but must be weighed and diluted. 

All chromatographic reference standards are supplied with a certificate of analysis certifying the identification and purity of the compound.
