Spectrometer and crystal selection
Compare analytical lines across common WDS crystals, inspect spectrometer ranges, and see how line positions relate to usable instrument geometry.
Electron-probe training and WDS method exploration
Virtual WDS
Explore wavelength-dispersive X-ray spectrometry before stepping onto the instrument. Virtual WDS helps students, instructors, and analysts see how crystals, lines, spectrometers, backgrounds, and overlaps shape real analytical decisions.
Built for classrooms
Explain WDS choices visually.
Useful for labs
Prepare method discussions away from the microscope.
Desktop software
Runs locally with offline activation.
Capabilities
Make WDS behavior visible, testable, and teachable.
Virtual WDS is designed around the practical questions that come up when setting analytical conditions or teaching electron-probe microanalysis. It gives instructors and analysts a place to explore line choice, crystal selection, spectrometer limits, interferences, background behavior, and method settings before instrument time is involved.
Peak overlaps and high-order lines
Visualize interfering lines, high-order reflections, and nearby absorption edges so students and analysts can understand why a line is easy or difficult to measure.
Background placement
Explore background positions around analytical peaks and show how continuum shape, neighboring lines, and spectrometer limits affect background choices.
Analytical conditions
Use accelerating voltage, beam current, PHA settings, detectors, crystals, and concentration inputs to demonstrate how method parameters change what is practical to measure.
Periodic-table driven exploration
Select elements from a periodic table workflow, build up candidate analyses, and immediately connect composition to spectral consequences.
EDS and teaching support
Use EDS display and demonstration-oriented modes to connect qualitative spectra with WDS planning, classroom explanation, and method review conversations.
Workflow
From question to spectrum in a few practical steps.
Use Virtual WDS to walk through analytical reasoning: choose elements, inspect possible lines, identify overlap risks, place backgrounds, and discuss conditions before collecting live instrument data.
01Select elements
Start from chemistry or a teaching example and choose the elements of interest.
02Inspect line choices
Compare line positions and crystal options on the simulated WDS plot.
03Evaluate interferences
Show overlaps, absorption edges, and high-order lines that complicate measurement.
04Discuss the method
Use the visual result to explain background positions and analytical conditions.
Example
Teach why the first obvious line is not always the best line.
In a course, training session, or pre-analysis discussion, Virtual WDS can start with a simple question: which X-ray line should be measured for a minor element when the sample also contains major elements nearby in energy?
Start with chemistry
Select the expected elements and concentrations, then ask which candidate lines are available on the installed spectrometers and crystals.
Show the spectral neighborhood
Display analytical lines, nearby peaks, high-order reflections, and absorption edges so the risk is visible rather than abstract.
Choose a defensible setup
Compare line, crystal, background, detector, and condition choices before committing instrument time to a method.
Turn setup into teaching
Use the simulated spectrum to explain tradeoffs, document reasoning, and prepare students or users for real WDS measurements.
Who uses it
One tool for teaching rooms, instrument labs, and software demonstrations.
Universities and courses
Give students a way to practice WDS concepts without scheduling instrument time for every learning exercise.
Electron-probe facilities
Use visual examples during method discussions, user training, and pre-session planning.
Commercial labs
Support internal training and explain analytical choices to colleagues or clients.

FAQ
Common licensing questions.
Can the software run without internet access?
Yes. Activation uses a license file generated from the Machine ID displayed by the software.
Is the license per user or per computer?
Pricing is for a non-renewing one-year license per computer. Additional computers require additional activations.
Can tax-exempt institutions purchase without tax?
Tax-exempt institutions should contact Aurum Scientific before purchase with their exemption documentation so the order can be handled appropriately.
What if a computer is replaced?
Contact Aurum Scientific with the order details and the new Machine ID. Replacement handling can be reviewed case by case.
