The first plasma-based instrument used direct current and also a microwave-induced system to generate the plasma. The utility of plasma for analytical chemistry was limited due to interference effects and plasma instability, hence the dominance of flame-based atomic spectrometry in the field of analytical chemistry. Although the flame spectrometer is still very effective today, the limitations of early plasma instruments were overcome with the replacement of direct current or microwave systems with inductively coupled plasma. In the 1980s the Inductive Coupled Plasma System became better known for its low cost which also required less time management than the others. Inductively coupled plasma can use sixty (60) elements simultaneously with a single plasma
