Abstract

Graphite pellet vaporization was evaluated as a method for solid sample introduction for ICP-MS. A detection limit of 0.1 ppb of Cd was obtained indicating that the technique might be very useful for screening. The accuracy was poor using the technique of external standards and four reference materials, suggesting that the technique of standard additions might be required if the technique was to be used for anything other than semi-quantitative measurements.
