A simple and convenient analyzing apparatus is provided which easily, conveniently, and efficiently collects a material in the state of fine particles adhered to a target object, extracts the object to be analyzed, and analyzes the extracted object. An apparatus for detecting fine particles in a gas which sucks the gas under measurement from the target object by using a suction pump, extracts the fine particles contained in the gas under measurement, and performs measurement by using a spectrometer is embodied such that an inertial impactor for collecting the fine particles having diameters not less than a specified particle diameter is disposed upstream of the spectrometer, the fine particles are collected in the fine particle collector of the inertial impactor, the collector containing the collected fine particles is heated such that the collected fine particles are vaporized into a gas, and the vaporized fluid to be examined is supplied to the spectrometer to be measured thereby.

What is claimed is: 1. An analyzing apparatus comprising: a recovery unit for recovering a gas containing fine particles; a collection unit for collecting said fine particles from the gas recovered by said recovery unit; and an analysis unit to which components of said fine particles collected by said collection unit and vaporized are introduced, wherein said collection unit has an ejector for ejecting the gas from said recovery unit, a fine particle collector disposed in opposing relation to said ejector to cause a collision between said fine particles in said gas, an exhaust flow path in which the gas that has passed through said fine particle collector flows, a vaporizer for vaporizing said fine particles collected by said fine particle collector, and an extraction flow path for guiding said vaporized components of said fine particle to said analysis unit. 2. The analyzing apparatus according to claim 1, wherein said collection unit has each of said vaporizer for the collected fine particles and said extraction flow path disposed on a surface of said fine particle collector opposite to a surface thereof formed with said ejector. 3. The analyzing apparatus according to claim 1, further comprising a carry-in mechanism for carrying in said fine particle collector having said collected fine particles from said collection unit and said vaporizer is formed to vaporize said fine particles of said fine particle collector that has been carried in. 4. An analyzing apparatus comprising: a recovery unit for recovering a gas containing fine particles; a collection unit for collecting said fine particles from the gas recovered by said recovery unit; an exhaust flow path in which the gas that has passed through said collection unit flows and a suction pump is disposed; and an analysis unit to which components of said fine particles collected by said collection unit and vaporized are introduced, wherein said collection unit has an ejector for ejecting the gas from said recovery unit, a fine particle collector disposed in opposing relation to said ejector to cause a collision between said fine particles in said gas, a vaporizer for vaporizing said fine particles collected by said fine particle collector, and an extraction flow path for guiding said components of said vaporized fine particles to said analysis unit, said analyzing apparatus having a first operation of operating said suction pump to exhaust the gas toward said exhaust flow path and collecting said fine particles in said fine particle collector and a second operation of lowering said suction pump after said collection to suppress the exhaust of the gas toward the exhaust flow path and increasing a temperature of said fine particle collector to a level higher than during said first operation to vaporize said fine particles. 5. A fine particle collecting apparatus comprising: a recovery unit for recovering a gas containing fine particles; and a collection unit for collecting said fine particles from the gas recovered by said recovery unit, wherein said collection unit has an ejector for ejecting the gas from said recovery unit, a fine particle collector disposed in opposing relation to said ejector to cause a collision between said fine particles in said gas, an exhaust flow path in which the gas that has passed through said fine particle collector flows, a vaporizer for vaporizing said fine particles collected by said fine particle collector, and an extraction flow path in which said components of said vaporized fine particles flow. 6. A fine particle collecting apparatus comprising: a recovery unit for recovering a gas containing fine particles; and a collection unit for collecting said fine particles from the gas recovered by said recovery unit, wherein said collection unit has an ejector for ejecting the gas that has passed through said recovery unit, a fine particle collector disposed in opposing relation to said ejector to cause a collision between said fine particles in said gas, an exhaust flow path in which the gas that has passed through said fine particle collector flows, a carry-in mechanism for carrying in said fine particle collector having said collected fine particles from said collection unit, a vaporizer for vaporizing said fine particles of said fine particle collector that has been carried in, and an extraction flow path in which said components of said vaporized fine particles flow. 7. A fine particle collecting apparatus comprising: a recovery unit for recovering a gas containing fine particles; and a collection unit for collecting said fine particles from the gas recovered by said recovery unit, wherein said collection unit has an ejector for ejecting the gas that has passed through said recovery unit, a fine particle collector disposed in opposing relation to said ejector to cause a collision between said fine particles in said gas, an exhaust flow path in which the gas that has passed through said fine particle collector flows and which is connecting to a suction pump, a vaporizer for vaporizing said fine particles collected by said fine particle collector, and an extraction flow path in which said components of said vaporized fine particles flow, said fine particle collecting apparatus having a first operation of operating said suction pump to exhaust the gas toward said exhaust flow path and collecting said fine particles in said fine particle collector and a second operation of lowering said suction pump after said collection to suppress the exhaust of the gas toward the exhaust flow path and increasing a temperature of said fine particle collector to a level higher than during said first operation to vaporize said fine particles.
