Lambda WDS Analysis System

The Lambda™ Wavelength Dispersive Spectrometry (WDS) Analysis System combines the EDAX WDS software with state-of-the-art spectrometers for improved accuracy and precision, guaranteeing the best results for your materials analysis.
Lambda WDS Analysis System
Designed for parallel beam operation, the Lambda spectrometers are available in models:
  • Lambda Plus - Delivers the maximum efficiency for transition element energies from 150 eV to 10 keV (B Kα to Ge Kα) using polycapillary optics.
  • Lambda Super - Dual optics system that provides the ultimate efficacy for light elements, especially B, C, N, and O using high-collection, reflective, patent-pending X-ray optics. This combined with the polycapillary optics, extends the high intensity up to 16 keV, for a total range of operation from 100 eV to 16 keV.

The compact design of the Lambda spectrometers allows for easy installation on any standard Energy Dispersive Spectroscopy (EDS) port. The Lambda spectrometers provide a perfect complementary tool for EDS analysis.

Overlap of silicon K and tungsten M lines are easily resolved using WDS instead of EDS.

Scanning Modes

The Lambda spectrometers can scan over the entire energy range to cover at least one X-ray line for each element in the periodic table.

Scanning mode options include:

  • Automatic acquisition of one or many EDS elements
  • Ability to customize the scan range to your application using spectral Swipe Mode or manual input
  • User-selectable step size and speed
  • Peak and background modes for a selection of elements
    • Define elements through an intuitive periodic table interface
    • Software suggests diffractor, peak, and background positions
Qualitative and Quantitative Analysis

The EDAX WDS software with Smart Quant provides users with qualitative and quantitative measurements. Simultaneously collect and overlay EDS and WDS data for easy qualitative confirmation. The analyst can select a technique (EDS or WDS) for quantification of a desired element to improve precision and detection limits.
