FIELD: spectral analysis. ^ SUBSTANCE: method uses one-electrode high-frequency plasma charge in mode of alternating pulses. In accordance to direction of gas along, perpendicularly or oppositely to plasma-generating electrode different constructions of device burners are used. Recording of radiation spectrums is performed in direction dependent on type of used spectrometer: perpendicular to said generated charge for slit spectrometer and in parallel for diaphragm spectrometer. ^ EFFECT: higher sensitivity, lower costs. ^ 2 cl, 4 dwg |
