Application Notes: Atomic Spectroscopy
Microwave Sample Preparation of Environmental Samples for Trace Metals Analysis
October 4th 2019Demand for trace metals analysis in environmental labs is growing due to stricter regulations, and the need for lower levels of detection increasing. Learn how the ETHOS UP is fully compatible with US EPA environmental methods with accurate and full control of the digestion process.
Analysis of Alloy Powders for Metal 3D Printing
September 25th 2019DMLS (Direct Metal Laser Sintering) is an industrial metal 3D printing method that fuses layers of fine metal powder particles, creating a metal part layer by layer. This report describes the analysis of alloy powders used for 3D printing.
High Voltage Accuracy and Precision on Small Compact X-ray Source
September 1st 2019Moxi™ X-ray source is calibrated to within ±250 V over all settings between 5 to 50 kV. This impressive accuracy and precision is achieved spectroscopically, by measuring an X-ray spectrum's bremsstrahlung edge and storing correction high voltage offset information on each source.
Analysis of Nuclear Power Station Colling Water Filters
August 27th 2019This application note demonstrates the analysis of copper and iron on Millipore and cation water filters by energy dispersive X-ray fluorescence, and highlights the performance of the Rigaku NEX DE Energy Dispersive X-ray Fluorescence Spectrometer.
A Simple, Low-Cost Approach to Improving ICP Productivity
August 26th 2019The Niagara Rapid Rinse is the simplest, lowest-cost method of improving throughput for ICP-MS applications. Time saved with the Niagara is typically 30%, with little to no changes to the current method settings and no degradation in performance.
Miniature 70 kV, 12W X-ray Source
June 1st 2017Recently, the compact MAGPRO’s maximum voltage was increased from 60 kV to 70 kV while maintaining the same size profile. This article highlights the advantages of 70 kV excitation of cadmium, an element of interest for Restriction of Hazardous Substances Directive (RoHS), at parts per million (ppm) levels.
The Measurement of Oxides in High Calcium Limestone Using Empirical Calibration.
December 1st 2016Limestone is widely used as the main ingredient in cement and mortar, and as an aggregate in concrete and asphalt for building roads. It iis also used as a soil conditioner and is the raw material for making quick lime and slaked lime. During mining and processing operations, limestone composition must be monitored and controlled to ensure proper quality and characteristics are achieved for a variety of products. This application note demonstrates the measurement of carbonates and major oxides in high calcium limestone by EDXRF using empirical calibration.
