Title: High-sensitivity analytical method for nonmetallic element
Inventor: YAMAGUCHI HIDENAO
IPC: H01J49/26
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To quantify nonmetallic elements such as oxygen, nitrogen, and carbon in a metallic material or a ceramic material with high accuracy to ppb level by using a argon-neon mixed gas containing neon at a specific ratio as a discharge gas. SOLUTION: Neon has higher ionization voltage than that of argon, thus neon is superior to argon for ionizing nitrogen or oxygen. When the argon-neon mixed gas is used as the discharge gas, if the neon content in argon is 2-3%, an electric discharge can be made while maintaining vacuum. When the discharge voltage and discharging current are optimized, oxygen, nitrogen and carbon can be quantified at high sensitivity. When the neon content in the mixed gas is below 2%, the quantification accuracy of nonmetallic elements such as oxygen, nitrogen and carbon has little difference from that in argon electric discharge. When the neon content exceeds 30%, evacuation cannot be maintained, and no analysis can be made.
