Micro-Z ULS

Wavelength Dispersive X-ray Fluorescence Sulfur (S) Analyzer

Measure ultralow sulfur (ULS) in petroleum fuels by ASTM D2622-10

Designed for ultralow level sulfur analysis of diesel, petrol (gasoline) and other fuels, the Rigaku Micro-Z ULS wavelength dispersive X-ray fluorescence (WDXRF) instrument features a novel design that measures both the sulfur peak and the back-ground intensity. The ability to measure and correct for changes in background intensity delivers a better net peak intensity measurement, resulting in superior calibrations and enhanced real world precision. Rigaku Micro-Z ULS complies with ASTM 2622-10, ISO 20884 and JIS K2541-7 methods.

Micro-Z ULS Overview

Superior optics for reliable sulfur analyses

The Rigaku Micro-Z ULS is the ideal solution for sulfur analysis of petroleum based fuels, with a lower limit of detection (LLD) of 0.3 ppm sulfur. Employing robust fixed optics in a vacuum environment, and featuring a specially designed doubly curved RX-9 analyzing crystal, the Micro Z ULS delivers consistent high sensitivity measurements.

ASTM D2622 performance for non-technical users

Specifically designed for non-technical users, all operations – from calibration through routine analysis – can be performed via the easy-to-use interface. And the analyzer can be powered by any standard “wall” AC outlet.

Dramituff Standard version

DRAMITUFF is a single component, air setting, castable. It has a very good abrasion resistance, cold crushing strength and chemical resistance. It can be hand packed or rammed in thin lining applications. DRAMITUFF is based on a proven binder system, which allows a wide range of water addition, giving working

Anchors for Fibers – Series D

Anchors produces refractory anchors for fibers (for insulating blankets, insulating boards/pannels, modules fibers). The fiber linings are common when we need the lining with good thermal shock resistance and a fast installation. Example : heat treatment furnaces. D1 : “Cerafix” type anchors «CERAFIX» type anchors : Anchors for fibers with

Support Brackets – Series C

Anchors produces refractory support brackets. Support brackets are used when the walls of the furnace are high.This enables to spread the weight on the refractory which reduces the risk of deterioration of the wall. They are also often placed around doors or < openings > to reinforce the refractory on

Brick Anchors – Series B

Anchors produces refractory anchors for bricks linings. B1 : “BSTP” type anchors BSTP1/BSTP2 : Brick anchors for linings composed of refractory insulating bricks, this type of lining is common in petrochemistry for example. Download “BSTP” B2 : “BR” type anchors Anchors for lining on dense

Castable Anchors manufacturer – Series A

Anchors produces refractory anchors for castable linings. Our range can suit all applications, We produce refractory anchoring systems in round and flat material, for hand welding, for gun welding, for all types of concrete density. A1 : “CH” type anchors CH1 – CH2 – CH4 – CH1RL : Castable anchor
