LGC has introduced a set of low sulphur certified reference materials to meet the needs of fuel testing laboratories when the new limits of 10 mg kg–1 sulphur in fuel come into force on 1 January 2009. These CRMs have been produced for use by laboratories to develop and validate reliable analyical methods to measure sulphur in fuels at these increasingly low levels. Of particular value to organisations in meeting the requirements will be the CRMs containing 8 mg kg–1 and 20 mg kg–1 in petrol and 10 mg kg–1 sulphur in diesel.
