Ionizing analysis apparatus

An ionizing analysis apparatus which ionizes a sample material contained in an electrolytic solution in a chamber, emits thus obtained ion, and then detects thus emitted ion, said apparatus comprising:

• a supply tube which supplies said electrolytic solution into said chamber and has an opening within said chamber;
• a needle which is disposed in said tube, has a tip projecting into said chamber through said opening, and is movable in a longitudinal direction thereof;
• and
• a nozzle for jetting out a gas against the tip of said needle from a direction substantially orthogonal to the moving direction of said needle.

An ionizing analysis apparatus which ionizes a sample material contained in an electrolytic solution in a chamber, emits thus obtained ion, and then detects thus emitted ion, said apparatus comprising:

• a supply tube which supplies said electrolytic solution into said chamber and has an opening within said chamber;
• a first needle in which at least a tip thereof is disposed within said chamber;
• a second needle which has a tip opposed to the tip of said first needle and is disposed within said tube so as to be relatively movable with respect to said first needle;
• and
• a nozzle for jetting out a gas against the tip of said second needle from a direction substantially orthogonal to the moving direction of said second needle.

An ionizing analysis apparatus which ionizes a sample material contained in an electrolytic solution in a chamber, emits thus obtained ion, and then detects thus emitted ion, said apparatus comprising:

• a supply tube which supplies the electrolytic solution into said chamber and has an opening within said chamber;
• a needle disposed within said chamber;
• takeout means for taking out a droplet of said electrolytic solution by said needle, wherein said takeout means comprises means for generating a Taylor cone by vibrating said supply tube so as to vibrate a liquid surface of said opening;
• and
• emitting means for emitting said droplet into said chamber by gas jetting out against said droplet taken out by said takeout means preferably with applying a predetermined voltage, corresponding to a charge polarity of said ion in said droplet taken out, to said needle.
