One is displayed liquid and is dodged fluid sample frame componentTechnical field
The present invention relates to liquid scintillation instrument technical field, particularly one displays liquid sudden strain of a muscle fluid sample frame component.
Background technology
Along with the omnibearing development of nuclear industry, the environmental pollution that it may bring becomes alarming problem day by day, and this makes people's more and more radioisotopic quantitative test in concern for the environment.There is multiple source in the radioactive nuclide be present at present in environment, the fall-out that such as nuclear weapon test stays, and the waste material of nuclear industry and non-core industrial discharge.Except some radioactive nuclide that nuclear device directly discharges, the fall-out that natural source and nuclear facilities produce is the main source of radiomaterial in terrestrial ecosystems.Because the existence of nuclear radiation dirt and nuclear industry emission, people are more deep than the research of other nucleic to the research of some radioactive nuclide.Liquid scintillation counting (LSC) is the important method of quantitative measurment radioactivity, by method nuclide identification such as activity measurements.Liquid scintillator measuring apparatus device is mainly used in the applications such as life science, Environmental radioactive monitoring, radioactive isotope application, Nuclear Power Industry and bio-genetics.
At present, liquid dodges spectrometer needs the multiple sample of batch analysis, adopts specimen holder input mode, because the specimen holder of charging and the mutual friction of levelling bench produce a large amount of electrostatic, interference Instrument background counting rate.
Summary of the invention
The object of the invention is to the deficiency that easily affects by frictional static for prior art and defect, a kind of frictional static that can reduce liquid scintillation spectrometer specimen holder and the liquid of displaying facilitating electrostatic to spread is provided to dodge fluid sample frame component, to reduce the interference of outer bound pair background sample.
Technical matters solved by the invention can realize by the following technical solutions:
One is displayed liquid and is dodged fluid sample frame component, it is characterized in that, comprising:
Rectangular parallelepiped sample box in opened type, described rectangular parallelepiped sample box inner chamber is arranged at intervals with some bottle covers along its length successively, each bottle cover bottom symmetrical is provided with the long turnover panel of first, second side of extending described rectangular parallelepiped sample box for a pair, first side in described rectangular parallelepiped sample box face is provided with signal light barrier corresponding on the position of each bottle cover, the first side of described rectangular parallelepiped sample box is also provided with scan code;
Vertical lifting bar, the masthead end of described vertical lifting bar is connected in the middle part of the bottom surface of described rectangular parallelepiped sample box, and the masthead end of described vertical lifting bar is provided with antistatic layer, and described vertical lifting bar is made up of conducting electrostatic materials.
In a preferred embodiment of the invention, described antistatic layer is made up of teflon.
In a preferred embodiment of the invention, described vertical lifting bar is made up of stainless steel.
In a preferred embodiment of the invention, first, second side of described rectangular parallelepiped sample box is respectively arranged with dog hole.
In a preferred embodiment of the invention, the both ends of the surface of described rectangular parallelepiped sample box are respectively arranged with prompting arrow.
In a preferred embodiment of the invention, described rectangular parallelepiped sample box adopts polyurethane material to make.
Owing to have employed technical scheme as above, beneficial effect of the present invention is:
At the bottom of the bottle of rectangular parallelepiped sample box of the present invention, long turnover panel is for reducing the friction of sample bottle, reduces electrostatic, thus realizes reducing the interference to the Low background of beta activity nucleic, reaches the background level requirement of Low background beta activity activity measurement.The signal light barrier of rectangular parallelepiped sample box realizes location, guarantees that sample bottle accurately puts in place; In addition, the top of vertical lifting bar is provided with antistatic layer, vertical lifting bar is made up of conducting electrostatic materials, reduces electrostatic and facilitates electrostatic to spread.

Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below.
See shown in Fig. 1 to Fig. 3, a kind of liquid of displaying dodges fluid sample frame component and comprises rectangular parallelepiped sample box 100 in opened type and vertical lifting bar 200, and rectangular parallelepiped sample box 100 adopts polyurethane material to make.Rectangular parallelepiped sample box inner chamber is arranged at intervals with ten bottle covers 110 along its length successively, and the internal diameter of each bottle cover 110 is 29mm.Each bottle cover 110 bottom symmetrical is provided with the long turnover panel 120 of first, second side 101,102 of extending rectangular parallelepiped sample box 100 for a pair, the effect of long turnover panel 120 is the frictions reducing sample bottle 300, reduce electrostatic, thus realize reducing the interference to the Low background of beta activity nucleic, reach the background level requirement of Low background beta activity activity measurement.First side 101 in rectangular parallelepiped sample box face 100 is provided with signal light barrier 130 corresponding on the position of each bottle cover 110, realizes location, guarantee that sample bottle 300 accurately puts in place.First side 101 of rectangular parallelepiped sample box 100 is also provided with binary coding 150.Conveniently use, the both ends of the surface 103,104 of rectangular parallelepiped sample box 100 are respectively arranged with prompting arrow (not shown).First, second side 101,102 of rectangular parallelepiped sample box 100 in the present embodiment is respectively arranged with dog hole 140.
The masthead end of vertical lifting bar 200 is connected in the middle part of the bottom surface 105 of rectangular parallelepiped sample box 100, and the masthead end of vertical lifting bar 200 is provided with antistatic layer 210, and vertical lifting bar 200 is made up of conducting electrostatic materials.Reduce electrostatic and facilitate electrostatic to spread.Preferably, antistatic layer 210 is made up of teflon, and vertical lifting bar 200 is made up of stainless steel, for external diameter is the cylindrical of 28mm.
When the present invention works, by the lifting of vertical lifting bar 200, rectangular parallelepiped sample box 100 is sent into measurement chamber, can measure sample bottle 300.Be provided with antistatic layer 210 between rectangular parallelepiped sample box 100 and vertical lifting bar 200, avoid traditional input mode and easily rub and produce the drawback of a large amount of electrostatic.
