METHOD OF OBTAINING LOCAL ELECTRIC DISCHARGE IN LIQUID AND DEVICE TO THIS END (VERSIONS) Russian patent published in 2009 - IPC G01N27/62 

FIELD: electrical engineering.

SUBSTANCE: invention is meant for use in determining elemental composition of a substance. The proposed method of obtaining local electric discharge in a liquid involves passing electric current through the given liquid using electrodes, separated by a partition wall made from dielectric material with a diaphragm, through which passes the liquid current conductor. An element made from current conducting material is placed in the zone of local electric discharge. Potential of this element is chosen based on maximum intensity of the local electric discharge while maintaining its stability. According to one version, the device which realises the proposed method contains a dielectric case with electroconductive liquid and electrodes, connected a high voltage source, immersed in the said liquid and separated by a partition wall made from dielectric material with a diaphragm. In another version the device for obtaining local electric discharge in a liquid has a case with electroconductive liquid and electrodes connected to a high voltage source. One of the electrodes is immersed in the liquid and the other is hermetically attached to the dielectric wall of the said case on the outside and is linked to the said liquid through a diaphragm, made in the said dielectric wall of the case. According to both versions of the device, an element made from current conducting material is put in the zone of local electric discharge.

EFFECT: invention increases intensity of spectral lines of a wide range of elements.
