For X-ray fluorescence (XRF), a common matrix effect interference involves particulates settling to the bottom of the sample cup and absorbing the X-ray signal which can lead to a biased result. While many D4294 instruments can correct for interfering elements, interferences that settle in crude oil can create challenging scenarios. Refineries and third-party certification companies using XRF for high-particulate samples have relied on centrifuging samples to ensure an accurate sulfur measurement.
Petra MAX is a multi-element D4294 analyser designed with a vertical sample introduction system to help eliminate biased results due to particulate settling and avoid the hassle of centrifuging samples before measurement.
