A novel gas inlet system for improved aerosol entrainment in laser ablation inductively coupled plasma mass spectrometry

Computer simulations of sample chambers for laser ablation–inductively coupled plasma spectrometry

“…Bleiner [23] developed a novel ablation cell design, the 'piston cell', realized from a plastic syringe of 50 mL. The flow through such a cell was improved with a plug flow flush, using a patented nozzle device [33]. The simulation results showed that the flow characteristics are axi-symmetric and a plug flow profile is created which explains why the extraction efficiency is factor of 6 higher than the standard chamber designs discussed above.…”

“…After counting the tree rings, a mark was applied onto the rail indicating sets of rings at 5-year intervals. Two samples in rails fixed in a metal holder were placed onto an aluminium support in the cavity of the sampling cell designed by the EMPA (Bleiner and Altorfer, 2005).…”

“…An Nd : YAG laser Perkin Elmer/Sciex sampler 320 EMPA modified at EMPA (Wanner et al, 1999;Bleiner and Altorfer, 2005) was coupled to an ELEMENT 2 high resolution magnetic sector field ICP-MS (ThermoFinnigan). The use of the laser coupled to a high resolution ICP-MS is advantageous compared to determinations in previous studies, because it enables not only determination of metals but also elements such as P, S, and K which are inferred in quadrupole ICP-MS.…”

“…A stronger degree of dispersion can, therefore, only be achieved if a turbulent flow is established inside the ablation cell, passively, by a static inlet nozzle [28] or, actively, using a revolving device [29]. If no dispersive elements are implemented aerosols remain confined within cohesive fragments and filaments during their transportation to the ICP, similar to the plume of a candle burning off.…”
