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.
