Cyclone separator type mass analyzing system
View Patent ↗Provided is a small-sized mass analysis system capable of analyzing an analysis target system being under atmospheric pressure. The mass analysis system ( 7 ) has a cyclone separator ( 1 ) including a hollow shaft motor ( 19 ) for rotationally driving a turbo blade ( 17 ). Combining a mass analysis device with the cyclone separator makes it possible to remove dust and introduce into the mass analysis device a gas present in a region where the pressure in the cyclone separator is sufficiently reduced.
1. A mass analyzing system ( 7 ) comprising:
a cyclone separator ( 1 );
an analyzing apparatus introduction port ( 3 ) that is attached to the cyclone separator ( 1 ); and
a mass analyzing apparatus ( 5 ) that is connected to the cyclone separator ( 1 ) through the analyzing apparatus introduction port ( 3 ),
wherein the cyclone separator ( 1 ) comprises:
a swirl generating container ( 9 );
an intake port ( 11 ) that is attached to the swirl generating container ( 9 ) and is used to take a gas into the swirl generating container ( 9 ),
a swirl generating device ( 13 ) that swirls the gas taken into the swirl generating container ( 9 ), and
an exhaust port ( 15 ) that discharges a gas rotationally separated in the gas taken into the swirl generating container ( 9 ),
wherein the mass analyzing apparatus ( 5 ) comprises a vacuum system,
wherein the swirl generating device ( 13 ) comprises a turbo blade ( 17 ) and a hollow motor ( 19 ) that rotationally drives the turbo blade ( 17 ), and
wherein the turbo blade ( 17 ) is provided so that the rotation center of the turbo blade ( 17 ) is coaxial with the center of the analyzing apparatus introduction port ( 3 ).
2. The mass analyzing system according to claim 1 , further comprising:
an ionization portion ( 21 ); and
a guide wire ( 23 ),
wherein the ionization portion ( 21 ) is provided inside the swirl generating container ( 9 ) and is used to ionize the gas taken into the swirl generating container ( 9 ), and
wherein the guide wire ( 23 ) is provided so as to be coaxial with the analyzing apparatus introduction port ( 3 ) inside the swirl generating container ( 9 ) and is used to attract the gas ionized by the ionization portion ( 21 ).
3. The mass analyzing system according to claim 1 , further comprising:
an electrical discharge portion ( 25 ) that is installed inside the swirl generating container ( 9 ).
4. The mass analyzing system according to claim 1 , further comprising:
an emitting portion ( 27 ) that is installed inside the swirl generating container ( 9 ) so as to emit molecules or ions from the swirl generating device ( 13 ),
wherein the analyzing apparatus introduction port ( 3 ) is installed at a position facing the emitting portion ( 27 ).
5. A method of analyzing a substance contained in a gas, the method comprising:
rotationally separating a target gas contained in a gas by a cyclone separator ( 1 );
introducing the rotationally separated target gas into a mass analyzing apparatus ( 5 ); and
analyzing a mass of a substance contained in the target gas introduced into the mass analyzing apparatus ( 5 ),
wherein the rotationally separating of the target gas comprises ionizing the target gas contained in the gas and accumulating the ionized target gas at the center portion of the cyclone separator ( 1 ) by swirling the target gas contained in the gas, and
wherein in the introducing of the rotationally separated gas into the mass analyzing apparatus ( 5 ), the target gas, which is in a low-pressure state due to the rotationally separating of the target gas and is ionized and accumulated at the center portion of the cyclone separator ( 1 ), is introduced into the mass analyzing apparatus ( 5 ).
