X-ray Fluorescence (XRF) is a non-destructive elemental analysis technique used to determine the chemical composition of metals, powders, minerals, catalysts, pharmaceuticals, and many other materials.
Optical Emission Spectroscopy (OES) is an elemental analysis technique commonly used in the metals industry for accurate determination of alloy chemistry and certification of production materials.
Yes. VPrep offers elemental composition testing for a wide variety of samples using advanced ED-XRF and WD-XRF instrumentation.
ED-XRF generally offers lower operating costs and ease of use, while WD-XRF has better resolution and typically provides higher analytical performance and lower detection limits.
We support metallurgy, mining, recycling, aerospace, automotive, pharmaceutical, environmental, research and development, electronics, and manufacturing industries.
VPrep supports a wide range of XRF systems including Rigaku, Malvern Panalytical, Shimadzu and Thermo Fisher Scientific instruments for both energy-dispersive XRF (ED-XRF) and wavelength-dispersive XRF (WD-XRF) applications.
