Sample Preparation Method for Mercury Analysis in Reagent Chemicals by ICP-OES
November 1st 2015Efficient and accurate measurement of mercury concentration is a challenge. A direct sample preparation method for reliable ICP-OES mercury measurement would be invaluable to chemical manufacturers, testing laboratories, and other industries. Historically, ICP-OES Hg measurements have been plagued by poor Hg detection limits, severe carryover effects, and sample instability. In this study, we present a method of sample preparation for ICP-OES mercury analysis in various reagent chemical compounds. This sample preparation method is straightforward and direct, allowing mercury analysis in a variety of reagent chemicals without digestion.
