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.

Real-world precision.

Lower limit of detection: 0.3 ppm S
Compliant with ASTM D2622-10, ISO 20884, and JIS K2541-7

Rigaku Micro-Z ULSD wavelength dispersive X-ray fluorescence sulfur analyzer

A novel design for ultra-low level sulfur analysis

Designed for ultra-low level sulfur analysis of diesel, petrol (gasoline), and other fuels, the Rigaku Micro-Z ULSD sulfur analyzer and wavelength dispersive X-ray fluorescence (WDXRF) instrument features a novel design that measures both the sulfur peak and the background intensity.

Background correction

Measure the sulfur peak.
Correct the background.

A better net peak intensity measurement, from a single design decision.

The sulfur analyzer’s ability to measure and correct for changes in background intensity delivers superior calibrations and enhanced real-world precision.

Lower limit of detection.

With a lower limit of detection (LLD) of 0.3 ppm S, the Rigaku Micro-Z ULSD sulfur analyzer complies with ASTM 2622-10, ISO 20884, and JIS K2541-7 methods.

Designed for

  • Diesel
  • Petrol (gasoline)
  • Other fuels

Precision + Range

Fixed optics.
Switchable focus.

A 40 kV chromium-anode X-ray tube excites the sample at up to 40 W, read by a doubly curved RX-9 analyzing crystal and sealed proportional counter. Fixed optics with a switchable receiving slit select between peak and background, with samples analyzed in air while the optics themselves run under vacuum from an external pump. The analyzer uses a single measurement position with a standard 35 mm cup, keeping running and consumable costs low.

Built for non-technical operators.

Every step from calibration to routine analysis runs through the same on-board interface, powered by any standard wall AC outlet.

At a glance

  • LCD display + membrane keypad
  • Up to 10 calibrations, 30 standards each
  • Selectable analysis time, up to 900 s
  • Optional thermal dot printer
