EDAX Neptune System (EDS-WDS)
Model PV7400
Rapidly determines the most accurate (major, minor, and) trace element composition data so you can promptly make decisions.
Advantages
EDAX® Neptune is a materials characterization solution that provides users with the power and flexibility of energy dispersive x-ray spectroscopy (EDS) with the resolution, precision, and improved detection limits of wavelength dispersive spectroscopy (WDS). Together, the two techniques allow you to rapidly determine major, minor, and trace element composition with the highest accuracy, enabling prompt decisions to be made. Each technique can be used independently, or the data can be collected simultaneously to provide the most in-depth understanding of your sample’s composition.
Improves result accuracy by resolving EDS peak overlaps with up to 15x better energy resolution
.svg%3Fiar%3D0&w=3840&q=75)
Detects minor and trace elements reliably with improved spectral resolution and peak-to-background ratios (P/B)
Supplies results up to 8x faster than other systems by collecting more x-rays with the EDAX Lambda spectrometers
Provides precise quantitative results using a proven analytical algorithm
Correlates with other techniques to perform the most comprehensive analysis available
Avoids operator error and analysis pitfalls by capturing EDS and WDS data simultaneously
