Rigaku Micro-Z ULSD / Sulfur analyzer

Ultra-low sulfur.
Real-world precision.

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

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
