LGC has extended its range of certified reference materials (CRMs) for ethanol in water, intended for the calibration and validation of methods for the determination of ethanol in biological fluids.
The two new reference materials have been produced at concentrations of 50 and 67mg of ethanol per 100ml - in line with the current blood and urine alcohol limits for drink-driving in many European countries.
These materials have been produced under LGC's accreditation to ISO Guide 34 for the production of reference materials.
The reference materials are said to meet the stringent technical guidelines of European Reference Materials (ERM) status and the data were accepted as complying with the principles laid down in the technical guidelines of the ERM co-operation agreement between LGC, BAM and IRMM.
The forensic ethanol reference materials were produced and certified by LGC through chemical oxidation of the ethanol present with excess potassium dichromate followed by titration with acidified iron ammonium sulphate.
