| In this paper, the authors compare the performance of Double Pulse LIBS to a technique they have call Combined Pulsed Plasma (CPP) for the determination of C in soils. In CPP, a capacitor is positioned so that it discharges through the LIBS plasma. This gives additional energy to the plasma, resulting in a longer lifetime and more intense emission peaks. Analysis was made of soil samples collected from the field (and the Central Botanical Gardens of Belarus!) which were pressed into pellets. | |||||
