EDXRF App Note: Cement Analysis by the Fusion Method on Benchtop WDXRF Supermini200 According to ASTM C114-11 Rigaku Corporation Application note XRF5046 demonstrates quantitative analysis for Portland and aluminate cements by the fusion method according to ASTM C114-11 on the Rigaku Supermini200 bench-top sequential wavelength dispersive XRF spectrometer. The results demonstrate that the performance of the Supermini200 spectrometer exceeds the precision requirement defined in ASTM C-114-11, which covers chemical analysis of hydraulic cement. Download the app note Miniature 60 kV, 1000 µA, 12 W X-ray Source Sterling Cornaby, Moxtek The new 12 W source from Moxtek is meant for use in small bench top and portable XRF systems where small size components are valued. Its features are critical for more precise and faster XRF analysis of heavy and light elements at low concentrations. Download the app note Determination of Pb in Edible Oils and Fats by GF-AAS Shimadzu Monitoring edible oils is essential to ensure a safe, nontoxic, and regulatory-compliant product. Here, the lead content of various edible oils was determined using an atomic absorption spectrophotometer, as per AOAC Official Method 994.02. Download the app note Determination of Mercury in Soil Using Direct Mercury Analysis Jason Gerbino and Sumedh Phatak, Milestone Inc. This paper describes the importance of mercury analysis of soil samples and how direct analysis overcomes the challenges faced when analyzing mercury in soil and sediment using CVAA and ICP. Download the app note Ultra-Trace Mercury Determination in Bottled Water, EPA Method 1631, Using the Teledyne Leeman Labs QuickTrace® M-8000 CVAFS Jeff Forsberg, Teledyne Leeman Labs Mercury determination in water and foodstuffs is a crucial part of environmental monitoring. Mercury contamination may come from bottle production or the bottling process itself.  This application note demonstrates how the Teledyne Leeman Labs QuickTrace® M-8000 Cold Vapor Atomic Fluorescence Analyzer for ultra-trace mercury analysis in single gold amalgamation mode performed with US EPA Method 1631. Download the app note Initial Quantitative Measurements with Handheld LIBS Don Sackett, Suzanne Moller, Morgan Jennings, and Justin Spott, SciAps The analytical technique laser induced breakdown spectroscopy (LIBS) for elemental analysis is rapidly evolving from a laboratory-based to a field-able technology. Keys to this evolution include the development of more powerful yet compact, battery operable lasers, and combining the advancing laser technology with powerful processors and compact, high resolution spectrometers. The result is the first generation of truly handheld LIBS-based analyzers, such as the SciAps Z-500 LIBZ analyzer that has been utilized in a number of studies of different material types including alloys, ceramics, catalysts, soils, and glass sample types. This note presents the early quantitative results from several field tests. Download the app note   Portable Raman Spectroscopy in Archaeology and Art A.J.R. Bauer, PhD, TSI Incorporated Raman spectroscopy is an important instrument in the arsenal of art conservators and archaeologists. This application note summarizes some recent literature on the selection of portable instruments in this field and also documents some successful work done utilizing background correction to elucidate the composition of some challenging green pigments. Download the app note Ultrasensitive Detection of Mercury: Beyond FRET Cicely Rathmell, MSc; Ocean Optics Nanomaterial surface energy transfer (NSET), a variant of FRET, can be used to create a compact, cost-efficient, and ultrasensitive sensor for field testing of mercury in water, soil, and fish.
