Description
Technical field
The utility model relates to one kind loading net used in transmission electron microscope, in particular to it is a kind of to make in transmission electron microscope
Complementary type loading net.
Background technique
Usually transmission electron microscope experiment copper mesh used is done, the support grid of sample is as carried.If support grid copper material, just claim copper
Net, it is just corresponding to claim nickel screen, molybdenum net, golden net, nylon wire etc. if it is nickel, molybdenum, gold, nylon.
Support grid is used alone, also referred to as " naked net ".It is mainly used in biological sample preparation, slicer can be cooperated, used in the sink
" naked net " fishes for sample.Spray carbon or metal spraying processing are carried out again, are observed subsequently into Electronic Speculum.Most of transmission electron microscope sample are in sample preparation
When, in order to ensure sample can be mounted in " support grid ", one layer of organic film can be covered in " support grid ", referred to as " support film ".This tool
There is the support grid for supporting film, referred to as " support grid support film ".When sample contact support grid supports film, it can firmly be adsorbed on very much support film
On, it is unlikely to slide from the hole of support grid.To be observed in Electronic Speculum.
When sample is placed in Electronic Speculum, " support grid support film " can be irradiated by electron beam, will generate charge on organic support film
Accumulation, can also cause sample to discharge, and elegant sample occurs, bounce, supports situations such as film rupture.So people consider supporting
Carbon is sprayed on film, is improved the electric conductivity for supporting film, is reached good observing effect.It is this to pass through " support grid of spray carbon supports film ", letter
Claim " carbon support film ", general film thickness is 7-10nm.
In terms of cost of manufacture and using effect, copper mesh is most economical practical, so being generally used.Therefore, people often mention
" the copper mesh support film " that arrives, " carbon support film ", " carbon film ", " China, side film " etc., or even it is referred to as " copper mesh ", refer to this tool mostly
There is " the support film of copper mesh spray carbon ".Commonly referred to as " carbon support film ".
With the progress of science and technology, transmission electron microscope is more and more general in enterprise's scientific research field and universities' research institutes

Current installation total amount is also far from satisfying the vigorous scientific research demand in the whole world.Scientificlly and effectively improve the use of transmission electron microscope
Efficiency is beneficial to alleviate the testing requirement of current anxiety.
For current copper mesh as shown in Figure 1, for a round mesh sheet, periphery has round volume circle.One branch copper mesh is only capable of holding
Carry a sample.Cause to be wasted in sample preparation using the time there are about the transmission electron microscope of one third and vary, it is especially current
High pressure transmission electron microscope can only test a sample every time, put again after sample is placed on typical circular copper mesh and carry out taking out in vacuum chamber very
Do-nothing operation.And the transmission electron microscope of mainstream can not accomplish rapid vacuumizing at present, the pumpdown time is long, varies to waste significantly
Efficiency and testing efficiency.And rapid vacuumizing equipment purchase and maintenance and its valuableness, it can not popularize at present.How transmission is improved
The service efficiency of Electronic Speculum becomes us and is badly in need of the problem of thinking deeply.
