Abstract
Multielemental analyses of biological reference materials (hair, mixed diet and milk powder) by inductively coupled plasma-mass spectrometry (ICP-MS) were performed. Sample mobilisation directly from the solid by pulses from a free-running ruby laser was compared to conventional pneumatic nebulisation of the sample solution following acidic digesti on. Although inferior in both accuracy and precision, laser ablation I CP-MS offered rapid semiquantitative analysis with little or no sample preparation.
