Quality Control Test Standard A consists of:
1. Standards: Co (Cobalt) is compulsory for checking Energy Dispersive analysers. The customer can choose any other five from our lists, with the exception of the SRM 481, SRM 482 and SRM 1872.
2. Duplex Brass: 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.
3. Faraday Cage: A 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” - 150 microns.
4. Resolution Standard: Gold crystals 5-150nm on a carbon background which is useful for checking the performance of the SEM under high-resolution conditions i.e. finer than a 10 micron probe.
5. Silicon Magnification Grid: Silicon test specimen with a pitch of 10 μm and lines at 10 and 100μm. Useful for calibration and image distortion checks in the 100x to 1000x magnification range.
