New High-performance, Direct Excitation EDXRF Elemental Analyser for Field, Plant or Laboratory

Aug 19 2015

Applied Rigaku Technologies, Inc has announced its launch of the new Rigaku NEX DE direct excitation energy dispersive X-ray fluorescence (EDXRF) elemental analyser. Especially engineered for heavy industrial use, whether on the plant floor or in remote field environments, the NEX DE analyzer was developed to maximise flexibility and ease of use.

The instrument was designed for demanding applications or for situations where analysis time or sample throughput is critical, and is suitable for a broad range of applications, including exploration, research, bulk RoHS inspection, and education, as well as industrial and production monitoring applications. Its wide elemental coverage supports the rapid analysis of crude, oils, gasoline, fuels, lubricants and waste materials.

“The new NEX DE analyser is equipped with a 60 kV, 12 W X-ray tube to deliver significant improvements in elemental excitation ability and counting statistics, resulting in superior calibrations and precision for the most challenging measurements.” The high voltage, along with multiple automated X-ray tube filters, provides multi-element analysis capability for unmatched performance with low limits of detection (LOD). With direct excitation, energy requirements are significantly reduced, however. Because the sample-to-detector distance is less than one centimeter, less energy is required when compared to using secondary targets.

Next generation silicon drift detector (SDD) technology provides extremely high count rate capability with excellent spectral resolution. This enables the NEX DE to deliver the highest precision analytical results in the shortest possible measurement times. 

The system operates on the latest Rigaku QuantEZ analytical software, specifically designed for the Rigaku family of benchtop EDXRF analysers. Running under the Microsoft Windows operating system, on a laptop or benchtop personal computer (PC), the software offers all the functions required for calibration and routine operation. Based on the famous Rigaku easy-to-use flow bar interface, QuantEZ™ software walks the user through steps required to set up either an empirical or fundamental parameters application.

The optics are protected by a safety film that can be changed without tools. The system’s large sample chamber accommodates samples up to 30cm in diameter and 10cm tall, as well as a variety of single position and autosampler options. Removable autosampler trays are interchangeable and support 32mm, 40mm and 50mm cups or samples.

The NEX DE spectrometer is positioned to be the ideal solution for elemental analysis in basic quality control (QC) or its more sophisticated variants, such as analytical quality control (AQC), quality assurance (QA) or statistical process control.
