Throughout the world, legislation is being passed to reduce the allowable sulphur content in on-road diesel fuel to lower levels for environmental reasons. These regulatory changes have created a greater need for ULSD standards for use in petrochemical labs. VHG Labs (USA)
stocks a wide range of Sulphur Standards, QC Samples and Drift Monitors with concentrations ranging from 5 ppm to 6%. VHG manufactures and certifies sulfur standards from polysulfide oil as well as n-dibutyl sulfide under a quality control system that is registered to both ISO 9001:2000 and ISO 17025:2005. All VHG standards are accompanied by a COA that states the traceability to NIST SRMs.
