A range of isotopically labelled internal standards for toxicology analysis and research by LC-MS/MS and GC-MS/MS including the common Benzodiazepines. 13C and 15N internal standards enable the accurate determination of the analyte of interest and provide the advantage of co-elution with analyte, correction for sample to sample matrix variation, no loss of deuterium on the instrument or in solution and no detectable unlabelled material. Many standards are offered in ready to use certified solutions but please don’t hesitate to contact us if you are unable to find the standard that you need and we'll be delighted to check on its availability. Please note that many of these products can be considered Controlled Substances and may require licensing with the appropriate authorities prior to shipment.
