Ethyl-β-ᴅ-glucuronide, 1 X 1 mL (E-015-1ML)

This Certified Reference Material is widely used in forensic analysis and clinical toxicology applications to determine blood alcohol content. Ethyl-β-D-glucuronide (EtG) is a water-soluble and stable metabolite of ethanol, used as a routine biomarker in alcohol abuse monitoring. A very small fraction of ethanol undergoes degradation to EtG, and it can be detected in body fluids as well as hair. The certified reference solution (CRM) in solution can also be used as follows:Multi-residue analysis of different alcohol metabolites in human blood plasma and urine samples by ultra-high performance liquid chromatography (UHPLC) combined with tandem mass spectrometry (MS/MS)Optimization of a supercritical fluid chromatography-tandem mass spectrometric (SFC-MS/MS) method for the separation and quantification of highly polar drugs and their metabolites using an ion-exchange stationary phase from human urine samplesEvaluation of a paired ion electrospray ionization mass spectrometric (PIESI-MS) approach coupled with high performance liquid chromatographic (HPLC) procedure for the detection and measurement of drug metabolites in urine samplesAssess the impact of sample preparation of hair samples on the quantitative analysis of ethyl-β-D-glucuronide by ultra-high performance liquid chromatography-electrospray ionization-tandem mass spectrometryAnalysis of ethyl-β-D-glucuronide as a urinary biomarker in human urine samples by a benchtop gas chromatograph coupled with a mass spectrometer (GC-MS) Fully characterized under ISO/IEC 17025 and ISO 17034 accreditationAccompanied with a comprehensive Certificate of Analysis (CoA) with data on stability, homogeneity, accuracy of concentration, uncertainty, and traceabilityRigorously tested through real-time stability studies to ensure accuracy and shelf lifeGravimetrically prepared using qualified precision balances to ensure minimal uncertaintyFlame sealed under argon into ampoules for long-term shelf lifeOffered in a convenient, DEA-exempt format to improve laboratory efficiency
