Quality Control Testing Standard, Electron Microscopy Sciences
About this item
Standards Co (Cobalt) is compulsory for checking energy dispersive analyzers.
The customer can choose any other five from , with the exception of the SRM 481, SRM 482 and SRM 1872. A new product that allows the user of the Scanning Electron Microscope to check the performance of their instrument to make sure that it is working within the manufactures specification. A useful tool to all Scanning Electron Microscope users such as researchers, technologists, quality assurance departments, and SEM users with energy dispersive or wavelength dispersive X-ray systems fitted, because it enables them to readily assess the state of their instrument. Duplex Brass is used for checking the contrast efficiency of back scattered detectors and it is capable of detecting two major copper/zinc phases of 0.1 atomic number difference.
Faraday cage is used for measuring the current of the beam at the specimen plane. The beam of electrons is focused inside the hole by increasing the magnification so that when the hole fills the screen all the electrons are trapped and a true measure of current is achieved. The Hole size in FC 'aperture' is 150 µm.
S168T is a sample of gold crystals on a carbon background which is useful for checking the performance of the SEM under high-resolution conditions i.e. finer than a 10 µm probe. S1930 is a silicon test specimen with squares of periodicity 9.9 micrometers lines about 1.9 micrometers wide which has formed by electron beam lithography - used for magnification calibration and assessing image distribution.
All items above (QCT A) can be mounted on a block 25 mm Ø×5 mm thick.
Quality Control Test Set B
A larger version of the above is available with the following additions:
S168U Gold on Carbon used for low KV resolution check
1000 mesh and a 2000 mesh grid for magnification calibration of Scanning Electron Microscope
This larger (QCT B) version is mounted on a brass block 32 mm Ø×5 mm thick
