Rapid Determination of Trace Metals in Oil Using Handheld X-Ray Fluorescence Spectroscopy

July 1, 2014

Determination of trace metals in oil and petroleum typically is based on ICP-OES methods, requiring signficant sample preparation and expensive instrumentation. This article presents an alternative method, based on the use of a handheld energy-dispersive X-ray fluorescence analyzer, that involves minimal sample preparation, uses authentic standards for calibration, gives low parts-per-million detection limits, and provides significant time and cost savings.

X-ray Analysis Goes to Mars

July 20, 2011

This November, NASA's Mars Science Laboratory will be launched on a mission to Mars that will deploy a new rover, called "Curiosity." Curiosity will include several analytical instruments, including "CheMin," which uses X-ray diffraction (XRD) and also has limited X-ray fluorescence (XRF) capabilities.
