One is displayed liquid and is dodged fluid sample frame component
Technical 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.
