Depending on the plasma gas applied and element considered, detection limits typically varied from 200 2200 pg/s for Ar to 70 660 pg/s for He.
The adult was the most susceptible stage, however, immature stages responded differently to carbon dioxide gas applied at varying concentrations and pressure levels.
The source produces a large number of bright emission lines even at low pressures and the spectral distribution depends on the combination of discharge gas, applied magnetic field, applied power, cathode material, etc. [11, 12, 13].
The optimum operational condition obtained 80 g/m3 of ozone gas applied on leachate with 250 mg/l COD concentration during 60 min reaction time was required to achieve 26.7, 7.1, and 92 % removal for COD, NH3 N, and color, respectively.
The water expulsion treatment was conducted for four pore radii using the same sample: the values of ΔP gas applied were 146 , 485 1441, and 4000 hPa, corresponding to radii of 10, 3, 1, and 0.36 μm, respectively.
The formulations tested were sodium hypochlorite at 1, 3, and 5% chlorhexidine at 0.2% and 2% and ozone gas applied for different periods of time.
Helium was from SIAD GmbH (Vienna, Austria) and used in a purity of 6.0 as a carrier gas, applying a flow rate of 1.0 ml/min.
Nitrogen drying gas applied at the source entrance was heated to ca. 570 K at a flow rate of 10 L/min.
