Optimization of a novel ETV system for solid sample introduction into an ICP and its application to the determination of trace impurities in SiC

Data Processing Strategies for the Improved Analysis of Solder by Electrothermal Vaporization (ETV) Coupled to ICPOES

“…As one alternative, Verrept et al 23 proposed a "zeromass signal" approach; this involves the analysis of empty boats as blank measurements. This was adapted for the direct solidsampling of silicon carbide, 24 biological materials (such as fruit leaves, [25][26][27] wheat flour and sea lettuce 28 ), and environmental samples (sewage and sediment 28 ). Empty graphite boats can also be useful to monitor memory effects.…”

Optimization of the electrothermal vaporization conditions for inductively coupled plasma excitation spectrometry: Selective volatilization versus covolatilization approaches

“…Powder samples have been applied into the furnace as slurry [11], in form of pellet [12] and by means of different sample handling devices [13][14][15][16][17][18]. The present paper is restricted to the analysis of solution samples, either applied to the graphite tube wall, or into a graphite sample boat.…”

Electrothermal Vaporisation System Including In Situ Digestion for the Direct Determination of Lead in Botanical Samples by Inductively Coupled Plasma Atomic Emission Spectrometry

“…In recent years, inductively coupled plasma atomic spectroscopists have devised various direct sample introduction schemes: direct sample insertion, [1][2][3] electrically vaporised thin-film sampling 4 and electrothermal vaporisation using graphite furnaces. [5][6][7][8][9][10] Considering the ETV techniques combined with ICP atomic emission spectrometry (AES), these have further advantages of increased selective vaporisation of each analyte from matrix compounds and of independent optimisation of the ETV device and the ICP spectrometer.…”

“…Therefore, calibration using standard reference materials (SRMs) as solid calibrants is routine and has most frequently been used. 5,8,10 This method, however, requires careful selection of the SRMs. Their matrices should be similar to those of the samples.…”
