Abstract
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.
Claims5
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).
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).
