Innovation in Plasma Atomic Spectrometry from the Direct Current Arc to Plasmas on a Chip

Sono-induced cold vapour generation interfaced with capacitively coupled plasma microtorch optical emission spectrometry: analytical characterization and comparison with atomic fluorescence spectrometry

“…[14][15][16][17] Microplasmas generated in simple construction torches running at low power and low Ar/He consumption represent another advance in green analytical chemistry as they can be embedded in miniature analytical systems equipped with low resolution microspectrometers. [18][19][20] The analytical capability of various microplasma sources was demonstrated for the simultaneous multielemental analysis of liquid microsamples, simultaneous determination of As and Sb aer hydride generation or Hg quantication following CV generation. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] Until now, the possibility of coupling the sono or UV promoted CV generation with a microplasma/microtorch for mercury determination has not been investigated.…”

A novel analytical system with a capacitively coupled plasma microtorch and a gold filament microcollector for the determination of total Hg in water by cold vapour atomic emission spectrometry

“…Another way to achieve this high sensitivity could be battery-powered microplasma sources developed at atmospheric pressure equipped with microspectrometers. [26][27][28][29][30][31][32][33] This kind of novel instruments have as potential benefit portabilization and hence the perspective of developing on-site analytical methods. At the same time the cost in terms of equipment building and sample analysis is attractive as a result of extremely low Ar or He consumption.…”
