Behaviour of analytical spectral lines emitted by plasma pencil operated in a continuous and in a pulsed mode
Original language description
A modification of operating conditions by introduction of an admixture into the plasma gas stream was done for analytical application of plasma pencil ? chemical analysis. Excitation capabilities using sets of standard water solutions containing Na+, Li+, Ca2+, Mg2+, Cu2+ and Zn2+ ions, construction of calibration dependences in the range 1?100 mg/l and calculation of instrumental detection limits for these elements (3-sigma) were done in the continuous and in the pulse mode. Aqueous solution of calibration standard (0.6 ml/min) was delivered into a Scott chamber with a concentric nebulizer with efficiency of about 6 %. The produced aerosol was introduced by argon (0.3 l/min) perpendicularly into the plasma pencil operated in flowing argon (4 l/min). Electrical input power in the range of 120?140 W coming into the plasma guaranteed a stability of the discharge with water and sample load. To create a pulsed mode a carrying wave 13.
