METHOD OF INTEGRAL-SCINTILLATION EMISSION ANALYSIS WITH EVAPORATION OF SUBSTANCE FROM CRATER OF ARC DISCHARGE ELECTRODE Russian patent published in 2009 - IPC G01N21/67

Abstract RU 2368890 C1

FIELD: physics.

SUBSTANCE: invention relates to spectral analysis. During analysis, conditions are created for obtaining scintillation pulses of radiation due to fractional evaporation of chemical elements from a relatively deep crater of an arc discharge electrode, with prevention of interaction (contact) of plasma with substance in the crater, and using the relationship of temperature of the electrode crater and temperature of discharge plasma.

EFFECT: increased sensitivity and accuracy of substance analysis.
