Abstract
A flow injection analysis - inductively coupled plasma/mass spectrometry (FIA/ICP/MS) system is described using a Sciex Elan Model 250 ICP/MS system coupled with a peristaltic pump and injection valve. Sample volumes of 25 μl are injected and samples can be measured at the rate of one per minute. Addition of nitric acid to the carrier generally enhanced and stabilized the recorded signals. Also, the nitric acid tended to lessen interelement effects. Most interelement effects were fairly constant above 0.1 pm added element.
