Analysis of animal feeds by XRF

The analysis of finished animal feeds and premixes is demonstrated using EDXRF with indirect excitation and Fundamental Parameters software, suitable for feeds for cattle, pigs, chickens, ducks, and other fowl and livestock. The Rigaku NEX CG using the RPF-SQX Fundamental Parameters method yields excellent performance for the elemental analysis of various animal feed products. The use of RPF-SQX fundamental parameters eliminates the need for calibration standards. If desired, FP quantification can be optimized with Matching Libraries based on one or more assayed samples of the particular material type. These features make the NEX CG an ideal EDXRF tool for the elemental identification and characterization of animal feeds, raw meals and premixes throughout the animal feed industry to ensure proper nutrient balance and to screen for the presence of toxic elements.
