“…Such an approach permits to improve the sensitivity, considerably increases the sample throughput and reduces the risk of contamination/ losses. Thus, it is not surprising to see that different applications reporting on the determination of various PGMs by means of glow discharge mass spectrometry [8,9], laser ablation-ICP-MS [10][11][12][13][14] or optical emission spectrometry (OES) [15], electrothermal vaporization-ICP-MS [16,17], laser induced breakdown spectrometry [18,19] or X-ray fluorescence (XRF) [20][21][22] have been published. Obviously, only those techniques capable of providing a high sensitivity together with the maximum selectivity could be suited for this task.…”
