Interferences in Arc and Spark Emission Spectroscopy

In most modem laboratories, arc and spark emission is limited to the analysis of solid samples, because liquids are much more easily analyzed by ICP, MP, or DCP emission spectroscopy. 

Arc and spark emission spectroscopy is widely used for the qualitative, semiquantitative, and quantitative determination of elements in geological samples, metals, alloys, ceramics, glasses, and other solid samples. Quantitative analysis of more than 70 elements at concentration levels as low as 10-100 ppb can be achieved with no sample dissolution. The determination of critical nonmetal elements in metal alloys, such as oxygen, hydrogen, nitrogen, and carbon, can be performed simultaneously with the metal elements in the alloys.
