General description
A number of petroleum based oil products are formulated with
organo-metallic additives. These additives function as detergents,
antioxidants and/or anti-wear agents. Supelco and Analytical Services
(TX) have partnered to provide XRF calibration standards to measure the
amount of these additives in newly manufactured oil products, additives
and additive packages. Each standard is accompanied with a detailed
certificate of analysis (COA).
Set contains 17 bottles of engine oil with various wt% concentrations of calcium, phosphorus, sulfur and zinc.
