With both products:
- 1) Spectrum calibration with aluminum and copper.
- 2) Low energy spectrum calibration with carbon and aluminum.
- 3) Manganese full-width at half-max resolution measurement.
- 4) Low energy sensitivity test for monitoring contamination on detector window.
- 5) Two nickel grid sizes (high and low magnification) for checking image processing software and magnification calibration.
- 6) Backscattered electron detector performance
Specifications for the hole size of the grids:
40 µm x 40 µm (1,600 µm²) +/- 5%
18 µm x 18 µm ( 324 µm²) +/- 5%
Since the X-Checker comes on a standard 1" (25.4 mm) "metallographic size"
mount, it will fit into virtually any commercially manufactured SEM, from
very old to very new. For the operator of a busy SEM/EDS system, in a very
short period of time, one can confirm detector resolution (peak width at
half maximum) and energy calibration on either Mn or Ni and make sure the window is not
contaminated, check for low atomic number sensitivity and calibrate image
analysis software. Since the X-Checker products are made from an aluminum
SEM mount, there is aluminum "everywhere" so there is not a special
"sample" in the mount for aluminum.
