The choice between 3 resolution modes: low resolution (>300), medium resolution (>4000) and high resolution (>10000) is a prerequisite to eliminate interferences in the signal and consequently the basis for a quantitative analysis at trace and ultra-trace levels in a multi-element mode.</p> <p>Moreover, the multi-elemental detector has a speed that allows the monitoring of transient signals, as HPLC signals, among others. Our Element 2 is coupled to an HPLC system (Accela 600) and it is used as specific detector in the analysis of species of metalloids, as arsenic, in geological, environmental and biological samples.</p> <p class="classntxt1">We also have the possibility to couple a Thermo Scientific Trace 1310 gaschromatograph via heated transferline to the ICP mass spectrometer for the speciation of mercury.
