Spectroscopic analytical techniques are crucial for the analysis of environmental samples. This review emphasizes the latest advancements in several key spectroscopic methods, including atomic, vibrational, molecular, electronic, and X-ray techniques. The applications of these analytical methods in detecting contaminants and other environmental applications are thoroughly discussed.
The 2021 Emerging Leader in Atomic Spectroscopy Award
May 1st 2021L. Robert Baker, the 2021 Emerging Leader in Atomic Spectroscopy, applies ultra- fast, time-resolved X-ray spectroscopy to explore charge transfer at surfaces, to understand electron transfer, energy conversion, electrochemistry, and catalysis.
Analyzing Water Samples Using EPA Method 200.8 to Support the Lead and Copper Rule Revisions
May 1st 2021EPA Method 200.8 and the Lead and Copper Rule Revisions don’t allow use of modern ICP-MS technology with a collision cell. Instead, correction equations can be used to compensate for polyatomic interferences.
Multi-Quadrupole ICP-MS: Pushing Limits of Detection to the Next Decimal
September 1st 2020For a number of elements, spectroscopic interferences can have a significant impact on the ability to achieve low detection limits in ICP-MS. We investigate the mechanisms in multi-quadrupole ICP-MS that are designed to remove these interferences.
LIBS Imaging Is Entering the Clinic as a New Diagnostic Tool
July 1st 2020Great interest has recently aroused in the study of the dysregulation of chemical elements within tissues. Information about the distribution of elements in biological tissues can contribute to a more complete medical diagnosis, and can guide therapeutic procedures for many pathologies.
A Robust, High Performance, Revolutionary Demountable ICP Torch
February 1st 2020Glass Expansion designed and patented the D-Torch, a revolutionary, demountable torch. The D-Torch uses high-precision engineering to provide the benefits of a demountable torch, such as lower running costs, chemical inertness, and configurable injector geometry, without compromising usability, performance, or durability. In this report, we discuss the effects of harsh matrices on torches, as well as the features, benefits, and improvements in analysis achieved with the D-Torch.
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.
Cement Analysis by the Pressed Powder Method on Benchtop WDXRF According to ASTM C114-11
November 2nd 2016Cement is one of the most important materials for construction. ASTM C114-11 covers chemical analysis of hydraulic cement. XRF spectrometry is used for chemical composition analysis of cement due to its simple sample preparation and high precision. This application note demonstrates quantitative analysis for Portland cement by the pressed powder method according to ASTM C114-11 on the Rigaku Supermini200, a benchtop sequential wavelength dispersive XRF spectrometer.
Gold Recovery from Used Ore by EDXRF
September 13th 2016The measurement of gold is demonstrated in used ore material such as that from ore dumps and tailing piles. The recovery of uranium from the used ore material is also presented. The results how the Rigaku NEX DE EDXRF can achieve excellent results for monitoring and measuring the concentration of gold and other valuable elements in the recovery of used ore materials.
