Compass4294 Is Used To Analyze The Phosphorus Element Content In Edible Oils.

Monitoring the phosphorus (P) content during production is essential for ensuring the quality of edible oils. It serves as an indicator of phospholipid levels, which are critical to oil quality, and aids in overseeing the refining process, particularly during degumming. Our clients require a rapid and direct method to simultaneously measure a large number of samples. X-ray fluorescence (XRF) analysis offers a straightforward, quick, and non-destructive approach that accurately assesses the elemental phosphorus content in edible oils. The portable XRF device can evaluate the phosphorus concentration throughout the refining process—from crude oil to refined, bleached, and deodorized (RBD) oils. The elemental concentration in an unknown sample is determined by comparing its peak signal with that of a reference substance with known concentration. Calibration establishes the correlation between known concentrations and peak signals; its R² value indicates accuracy, with values closer to 1.0 being preferable. Multiple calibrations can be performed.

The following figure is the XRF calibration curve for the phosphorus element.
