Micro-Z ULSD Analyzer

Measure ultra-low sulfur (ULS) in petroleum fuels
JIS K 12541-7, ASTM D2622, ISO 20884,

Durable. Dependable. Design you can trust.

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. The sulfur analyzer’s ability to measure and correct for changes in background intensity delivers superior calibrations and enhanced real world precision. With a lower limit of detection (LLD) of 0.3 ppm S, Rigaku Micro-Z ULS complies with ASTM 2622-10, ISO 20884 and JIS K2541-7 methods.
