“…These attractive MIP features also limit the MIP's capability and its use mainly as a detector in gas chromatography applications. 3 Introduction of liquid into the low-powered MIP is challenging since the available power is insufficient for simultaneously performing de-solvation and excitation. The liquid feeding rate must be low enough for sustaining the plasma.…”

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.
