Performance-Based Ultra-Trace Mercury Determination in Coastal Seawater, BCR-579, EPA Method 245.7
Jeff Forsberg, Teledyne CETAC
Seawater analysis is a crucial part of environmental monitoring. However, it can present many obstacles for the analyst. It is a powerful tool used to gather information regarding the ecosystem. Contamination, interferences, and sample preparation are a few of the major obstacles that can arise when monitoring mercury at this level. Mercury is prevalent through point source contamination that often comes from industry and bio-accumulation. The purpose of this application note is to validate the capabilities of the CETAC QuickTrace™ M-7600 Cold Vapor Atomic Absorbance Analyzer in the ultra-trace ng/L range.

Analysis of Low Concentration Sulfur in Petroleum-Based Fuels by Benchtop WDXRF According to ASTM D2622-10
Laura Oelofse, Rigaku
Sulfur in petroleum-based fuels contributes to atmospheric pollution and is strictly controlled. Regulations of sulfur content in fuel oil, such as diesel fuel and gasoline, have been tightened. Control of sulfur content is therefore very important in refineries. This application note demonstrates quantitative analysis of low concentration sulfur in diesel fuel, gasoline, and kerosene according to ASTM D2622-10 on Rigaku Supermini200, a benchtop wavelength-dispersive X-ray fluorescence (WDXRF) spectrometer.
