Determination of Thallium in Brain Tissue by Stable Isotope Dilution and Field Desorption Mass Spectrometry
2014
Schulten, H.-R. | Lehmann, W . D. | Ziskoven, R.
The utility of field desorption mass spectrometry for quantitative metal cation analysis in forensic sciences is demonstrated by the determination of a lethal thallium level in the brain tissue of an experimental animal. Stable isotope dilution and accumulation of the electrically recorded field desorption ion currents with a multi-channel analyzer allowed a direct estimation of thallium in homogenized tissue samples without further pretreatment. Experiments with standard solutions revealed the limit of detection for thallium to be about 10pg of the metal cation.
