Supermini200 / WDXRF elemental analysis

Benchtop WDXRF.
Changes everything.

1/4 the size, about 1/2 the price of floor-standing WDXRF
Fully compliant with ASTM D2622 and D6443

Rigaku Supermini200 benchtop wavelength dispersive X-ray fluorescence spectrometer

Powerful, well-established elemental analysis

Wavelength dispersive X-ray fluorescence (WDXRF) is one of the most powerful and well-established techniques for elemental analysis. It has several advantages, including light element sensitivity, exceptional elemental resolving power, and low limits of detection. Historical drawbacks of the WDXRF technique have been that such instruments are typically large, expensive, and require special utilities. With a size that is 1/4 that of traditional WDXRF units and a price that is approximately 1/2 of floor-standing units, the Supermini200 benchtop spectrometer changes everything.

The X-ray fluorescence experiment

Expose. Emit.
Measure.

Every element leaves its own fluorescent signature.

The X-ray fluorescence (XRF) experiment begins with exposing a sample to high-energy photons from an X-ray tube, which induces transitions of electrons between atomic orbitals and results in the emission of fluorescent photons.

From photons to elemental composition.

By measuring the energy and intensity (count rate) of these photons, qualitative and quantitative information about the elemental composition is obtained.

The XRF experiment

  • High-energy photons
  • Electron transitions
  • Fluorescent photons

Precision + Range

One tube.
Oxygen through uranium.

A 200 W palladium-anode X-ray tube runs at 50 kV, 4 mA, exciting elements from oxygen through uranium. A programmable beam filter (Zr standard, Al optional) and a three-position crystal changer (LiF(200) and PET standard, RX25 and Ge optional) feed a flow proportional counter and scintillation counter, covering samples up to 44 mm in diameter and 33 mm tall on a 12-position auto-sampler with a 30 rpm sample spinner.

Runs without special utilities.

A rotary vacuum pump replaces the cooling water, plumbing, and external chiller that larger WDXRF systems typically require.

At a glance

  • Vacuum standard, helium optional
  • 15–28°C, <75% RH
  • Rotary vacuum pump, no chiller needed
  • 100 kg (220 lbs)

Measurement quality

Precision depends on
two primary metrics.

  1. 01

    Measurement Quality

    Usually judged as precision (repeatability), and a function of many factors.

  2. 02

    Elemental Peak Resolution

    One of the two primary metrics.

  3. 03

    Photon Counting Rate

    One of the two primary metrics.
