Title: Ionization and mass spectrometry apparatus for sample
Inventor: KATO YOSHIAKI
IPC: H01J49/42
Filed: 1996-11-01
Abstract: PROBLEM TO BE SOLVED: To ionize a sample stably by providing a member surrounding a space for spraying a sample, and means for introducing a gas forcibly into the spraying space from the outside. SOLUTION: When a gas, e.g. N2 or He, is stored in a gas reservoir 10 under pressure of 1atm or above, the gas is fed forcibly into an atomization chamber 8a through a gas flow-in port 9d, an annular gas flow-in port 9e and a plurality of gas flow-out ports 9f arranged on a circumference. When the gas is stored in the gas reservoir 10 under the pressure of 1atm, the gas is fed into the atomization chamber 8a depending on the pressure reducing state therein similarly to the natural supply system. The gas reservoir 10 is heated using a heater. According to the structure, gas supply to an atomized gas flow is not effected directly by the variation of the outside air and stabilized ionization can be realized.

Abstract: PURPOSE:To enable a user to be informed of the possibility or impossibility of using steam by arranging a reach signal retaining means, and a display means for performing first display when first reach signal is retained by the reach signal retaining means and performing second display when second reach signal is retained by the reach signal retaining means. CONSTITUTION:When a set temperature is the highest set temperature L6, then it is discriminated whether the then temperature Ta of a base 1 is a temperature T1 for first steam or higher, or not. Then, if Ta>=T1, the output of first reach signal '1' is directed to a RAM. Besides, when Ta<T1, then Ta is compared with a temperature T2 to be hard for the steam.
