Detections of elements and molecules in coffee beans were carried out using single ICP-MS/MS coupled with a laser ablation sampling technique. For elemental analysis, laser-induced sample particles were introduced into the ICP, where the elements were ionized as M⁺ through the hard ionisation achieved in the high-temperature and atmospheric-pressure plasma (ICP). For molecular analysis, volatile organic compounds (VOCs) which were released from the solid material through laser-ablation induced sample heating were introduced into collision/reaction cell (CRC), instead of the ICP ion source. The VOCs were ionised through ion reaction with <SUP>40<SUP>Ar<SUP>+<SUP>. The results obtained in this study clearly demonstrate that LA-ICP-MS/MS is now a rapid and versatile technique for detecting both elements and molecules in solid materials.
