GASEOUS SAMPLE INJECTION VALVE AND GASEOUS SAMPLE INJECTION METHOD USING SAME |
摘要 |
<p>The present invention relates to a gaseous sample injection valve. The gaseous sample injection valve includes: a middle body injecting a fixed amount of a gaseous sample into the vacuum chamber of a mass spectrometer, the middle body being constituted by a gaseous sample injection tube, a gaseous sample discharge tube, a storage part, and a vacuum chamber connection tube; an upper body accommodating a first solenoid coil, a first plunger, and a first packing; and a lower body accommodating a second solenoid coil, a second plunger, and a second packing. The gaseous sample injection valve according to the present invention may be miniaturized to utilize a lightweight portable mass spectrometer. Also, the vacuum pump may be reduced in load to extend the operation life-cycle of the vacuum pump. In addition, when the gaseous sample is analyzed by using the mass spectrometer, a uniform mass spectrum with respect to the gaseous sample may be obtained.</p> |
