Below, with reference to the accompanying drawings the present invention is described in detail.Fig. 1 is for a kind of detection of novelty and measure measuring system device example schematic by the active ion that ion gun discharged.
Be full of the source material S that can emit active ion in Sample sleeve (sample-holder) container 1.
Sample sleeve 1 is the hydrostatic column of the extension made from thermal resistance glass, installs with vertical mode usually.Sample sleeve 1 is equipped with active ion generating material S at least at the middle part.If desired, the bed of specimen material S can be clipped between the gas infiltration plate (does not have diagram), as the filter paper that is contained in top and bottom prevents moving of material S and diffusion.Sample sleeve container 1 is equipped with temperature measurer, as thermometer 2 and well heater such as electric resistance heater 3, the temperature of material S can be controlled in the scope of hope in this way.
When active ion is measured, the nonionic inert gas that is contained in the gas cylinder 4 is imported decarburization groove 6 to remove wherein contained CO by pipeline 5
2, remove CO
2Inert gas import the inlet that is contained in the Sample sleeve top by pipeline 7.When inert carrier gas flows when contacting with sample S, just entrained by inert carrier gas by the active ion that S emits.The inert gas of carrying active ion is discharged from the outlet of Sample sleeve 1 bottom, arrives the container 10 that distilled water 11 is housed through pipeline 8.Inert gas is discharged in the air by exporting 12 after blowing to distilled water 11 surfaces at last.Therefore, inertia with active ion be imported in the distilled water 11 so that the electric conductivity of distilled water increases with the growth of the time that is blown into of the inert gas of carrying active ion.Distilled water 11 in the container 10 remains on a specific temperature under the effect of constant temperature instrument 9.Be immersed in two electrodes 13,13 in the distilled water 11 ' link to each other with measuring instrument 14, to measure the electric conductivity of water.
The material of container 10 that distilled water 11 is housed is without any the factor of the electric conductivity that may have influence on distilled water, this point is very important, can produce certain ion as chamber wall and enter in the distilled water consideration based on this respect, although the deviation that meter 14 is produced can obtain correcting by blank assay, traditional glass material such as soda glass are inapplicable because it can discharge that the electric conductivity that causes water produces the basic ion of deviation.
Owing to the electric conductivity of water depends on that temperature changes, be crucial so under constant temperature, measure the electric conductivity of distilled water 11.Although have no particular limits, the electric conductivity of distilled water is measured temperature and is generally 20～22 ℃.
Therefore, preferably with the inert gas of carrying active ion to import in the distilled water 11, as 20～22 ℃ with the basic equal temperature of distillation water-bath 11 self-temperatures.For reaching this purpose, as shown in Figure 2, temperature controller is housed at the middle part of pipeline 8, temperature controller includes the spiral line type or the serrate pipeline 15 that are immersed in the calibration cell 16.

Because temperature controller 16 and Gas Flow Velocity Controller 17 have been installed, measured value is more stable, therefore uses the measured value electric conductivity of just can drawing itself and schemes over time.Therefore, the initial value of curve can be known definite.
Implement in this creationary assay method process, the active ion of being emitted by specimen material S is carried by the nonionic inert gas as carrier gas and carries.Because the material S active ion of emitting is few, be obtain accurately, and the electric conductivity numerical value that can reappear, any material that carrier gas itself does not have active ion fully or do not have finally to produce an active ion is very important.Suitable inert gas comprises the potpourri of nitrogen, oxygen, hydrogen, helium, neon, argon gas and above-mentioned gas.If ionic species CO
2Can be removed fully in de-carbon groove 6, conventional method is that air is as vector gas.The air de-carbon can be by making air and organic amine compound such as triethylamine solution, solid alkali metal oxyhydroxide such as KOH, and contacts such as reinforcing yin essence ion exchange resin are carried out.
