Benchtop single element wavelength dispersive XRF analyzer

High-precision, high-sensitivity elemental analysis

Mini-Z series

A series of compact benchtop wavelength dispersive XRF analyzers, the Mini-Z series of analyzers are designed for analyzing specific single elements. Since the optics are optimally configured to a particular element, this series allows for high precision and low detection limits.

High precision single element analysis

Mini-Z can be configured as a Si analyzer (e.g., for coated Si on paper or plastic), an Al analyzer (e.g., for coated Al on paper or plastic), a Ni analyzer, (e.g., for Ni coating or plating), a Cl analyzer, a P analyzer (e.g., biofuels) or a Zr analyzer (e.g., for Zr coating).

Self contained elemental analyzer

The Rigaku Mini-Z series benchtop WDXRF spectrometers are completely contained X-ray generating systems. Interlocks and safety "X-RAY ON" indicators are present to protect operators from exposure to X-rays being produced. The spectrometers meet all North American safety codes and are CE marked.

Mini-Z series applications

10-Day repeatability data from the optimized Mini-Z Sulfur Analyzer on a 1 ppm ultra-low sulfur Conostan diesel standard

The petrochemical industry has been put under more and more pressure to certify low sulfur content in all types of fuels. The reasoning behind these tighter regulations is to ensure the least amount of negative environmental impact. The current restriction has set the maximum allowable sulfur at less than 15 ppm, with trends heading towards less at 5 ppm allowed in the near future.

Analysis of P, S, Cl in biodiesel

Phosphorus in biodiesel, which comes from lipids in the fuel, is harmful to diesel engines, so control of phosphorus content is crucial. Sulfur content in the raw material is very low, which means that the content of sulfur in biodiesel is also very low. However, since the sulfur contents in regular gasoline is regulated for environmental reasons, the content of sulfur in biodiesel oil is regulated as well.

Precision data from the Rigaku Mini-Z Sulfur Analyzer for ultra-low sulfur levels in fuels

Today's petrochemical market has been regulated to produce lower sulfur levels in all variety of fuels. This legislation has impacted manufacturers of diesel and all grade fuels that keep the U.S. infrastructure functioning. The current ranges for sulfur content in all grade fuels by WDXRF analysis are listed below:

Sulfur in Automotive Fuels with Mini-Z Sulfur (ASTM D2622) - 1035

This application note demonstrates that Mini-Z Sulfur Analyzer can meet the requirements of ASTM D2622-10.

Why do we buy one brand of canned food over another?

One of the reasons some foodstuff brands are so successful is their taste, making their recipes closely guarded company secrets. A lot of effort goes into developing a winning recipe and making sure that that same flavor safely makes it to our tables is what the food packaging industry is all about. The lowly tin can has been with us since 1812, but it has evolved from simple tinplated steel to now including a zirconium passivation film applied over the tinplate to further protect the food from spoiling and in preserving its flavor.
