'Petroleum products, such as oils and
fuels, are tested throughout their lifespan, from the time oil is taken from
the ground to beyond the petroleum recyclers. The concentration of contaminants
and trace elements is vital in ensuring the quality of oil and petroleum
products.
Our OIL proficiency testing (PT) scheme is designed specifically to assist
chemists and engineers working in refinery, fuel, used oil and lubricant
laboratories to meet regulations, while our Instant Feedback PT program is
intended to provide laboratories with a method to monitor their performance and
prove analytical competency.
