Abstract

Determination of traces of metals in gases is achieved by using a combination of a Pyrex Gas Washing System and ICP-MS methods. A special purge and blank installation is designed to clean the system with purified Helium (6N). Three 125-ml bubbler tubes in series with a 20 ml of nitric acid (~20%) are used to capture the metals carbonyl in carbon monoxide. The metals dissolved in nitric acid are analyzed by ICP-MS (Agilent 7500ce). This method is able to achieve detection limits down to 1 10-10 mol/mol. Theoretically, the detection limits could go lower, but they are typically limited due to sample contamination. The experimental results show that this method provides a cost-effective approach to measure the traces of metals in gases quickly and accurately.
