Agilent 710-ES Determination of Mercury in Certified Reference Sludge Application Note
The document details the determination of mercury levels in solid wastes, specifically sewage sludges, which often contain high concentrations due to environmental contamination. It highlights the utility of vapor generation techniques coupled with Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) for measuring mercury at low concentrations typically found in environmental analysis.
The note presents a specific procedure using an Agilent 710-ES equipped with a megapixel CCD detector and an Agilent VGA-77P Vapor Generation Accessory. It outlines the operating conditions for both the ICP instrument and the VGA, including gas flows, power settings, and pump rates. The document also covers sample preparation methods involving acid digestion of NBS 2781 (Domestic Sludge) reference material and reports detection limits and analysis results.
