Description
UOP 848 – Nickel, Vanadium, Iron, Lead, Copper and Sodium in Gas Oils by AAS
This method is for determining nickel, vanadium, iron, lead and copper in gas oils by graphite furnance electrothermal Atomic Absorption Spectrophotometry (GFAAS) at levels below 2000 ng/mL (approximating mass-ppb). For determination of higher levels, see UOP 800. Sodium content, expressed as g/g (mass-ppm), is determined directly by flame AAS. The lower limit of detection for all metals, including sodium, ranges from about 2 to 20 ppb depending on the element sought.
