ICP-MS: Out of the Box Solutions for not so Common Problems

1. Solutions for high concentrations assay using inert gases in a CRC. ICP-MS is a highly sensitive technique and mostly used for low concentration determination. In order to evaluate higher concentrations, dilution is needed, but a higher dilution factor, especially serial dilution, accumulates inaccuracies. We used an inert gas to eliminate the need for high dilution and allow better accuracy and less contamination.

2. Overcoming carryover in halogen determination.
Iodine has a very long carryover time in the presence of nitric acid which is a common acid used in ICP-MS analysis. We used an alkaline solution to lower the carryover time to allow a fast & accurate analysis method.
