“…An error of at least 20% in excitation temperatures, calculated from Boltzmann plot and the line-pair method, must be allowed. 11 The excitation temperatures obtained in this work agree within 10% of each other. The excitation temperature serves as a guide to the ability for the atom source to excite electronic transitions.…”

Plasmas 23, 043504 (2016) A low powered (<90 W) microwave-induced plasma has been generated at atmospheric pressure by using a Beenakker cavity, a laboratory constructed torch, and a gas mixture of argon (400 ml/min), hydrogen (100 ml/min), and air (130 ml/min). This plasma has an excitation temperature of 3300-3500 K, electron number density of 7 × 10 14 cm −3 , and easily accepts direct methanol and ethanol introduction with a 1 ml/min solution nebulization rate. Detection limits (3σ ) obtained from the atomic emission signals of Li, Sr, and Cr in water are 15, 120, and 290 ng/ml, respectively. Similarly, detection limits for the metals in methanol are 15, 120, and 260 ng/ml, respectively, and in ethanol they are 25, 360, and 330 ng/ml, respectively. The linear dynamic range is greater than three orders of magnitude.

“…In 1975, the concept of temperature applied to high‐temperature excitation sources was considered, as were arc plasma jets . Following on from this, microwave plasma became a standard reactive species 'precursor' source in SIFT‐MS, and after Duan et al introduced their microwave‐induced plasma desorption ionization (MIPDI) source for ambient mass spectrometry, many groups used the afterglow of a 'surfatron' .…”

“…The most widely applied technique is inductively coupled plasma optical emission spectrometry (ICP-OES), which is nowadays a routine method for the quantitative determination of elements from solutions [4]. Nearly together with the ICP, in the 1970s, the microwave excitation sources had been developed and tested [5,6], which application possibilities were discussed in several papers so far [7][8][9][10][11]. The conventional MIP instruments operate on a lower electric capacity and gas flow compared to the ICPs, and their analytical performance is lower due to the lower thermal stability and matrix tolerance of the applied emission source [12].…”

ABSTRACT. In this study, the method development is described for the multi elemental determination of organic rich soil reference material (BCR 700) by the new microwave plasma atomic emission spectrometry (MP-AES). Two sample preparation methods were compared (open vessel digestion on a hot plate and closed vessel microwave assisted digestion) for the BCR sample and EDTA extraction was carried out. The recoveries were tested by MP-AES and inductively coupled plasma optical emission spectrometry (ICP-OES) method to investigate whether the more cost-effective nitrogen supplied microwave plasma is appropriate for the elemental determination of digested organic rich soil samples. The BCR 700 sample was not certified for digestion methods yet similar sample pretreatment is present in the literature with which a good agreement was found. Our results also correlated with the values provided in the certification of the BCR 700 material for EDTA extraction. It was found that the microwave plasma is an effective and lowcost alternative of ICP-OES for soil analysis and with the convenient atmospheric digestion even the organic rich soil samples can be prepared prior to the elemental determination. However, the microwave assisted digestion is faster and easier to conduct. The limit of detection values of the measured elements by MP-AES are sufficiently low for the micro element determination of soils (Cd 70 µg kg -1 , Cr 5 µg kg -1 , Cu 25 µg kg -1 , Mn 12.5 µg kg -1 , Ni 45 µg kg -1 , Pb 220 µg kg -1 , Zn 155 µg kg -1 ).
