PLASMA CHROMATOGRAPHY DEVICE AND ION FILTER SELL

摘要

The present invention relates to a device for analyzing a substance contained in the air, and more particularly to a filter cell plasma ion chromatography apparatus and hence for the quantitative analysis of the compounds in the atmosphere.; In the ion filter cell of the plasma chromatography apparatus for the quantitative analysis of plasma chromatography apparatus and the ion filter cell, hence in accordance with the present invention are the compounds in the atmosphere, the air in which the ion filter cell is supplied to the ion filter cell supply, and for selectively intake to the compound molecule contains on supplied to heat the air sucked from the suction nozzle assembly and the suction nozzle assembly including a heater for activating the molecules containing compound in the air atmosphere membrane assembly and the membrane ionizing part and is opened for a predetermined period of time a plurality of electrode rings and the shutter grid to maintain a constant flow rate of the compound ionized by the ionization part to the compound molecules to be absorbed from the assembly ionized using a radioactive isotope and the insulating ring are alternately doedoe coupled to said ring electrode, respectively Which is a resistor is connected, by a DC voltage applied to the resistor is generated in the drift tube and the ion filter cells outside to control the moving speed of ions coming from the shutter grid to remove noise from entering, and maintains a constant electric field the aperture is characterized in that it comprises a collector for detecting the mass of the ion current pulses generated by the grid and the ions passing through the ion filter cell.; Therefore, by forming a uniform electric field in the ion cell filter has the effect of enabling more accurate measurement of the compound.
