|From the leader in calibration standards for electron
microscopes comes the calibration alignment tool users of small
spot XRF systems have been asking for, the Micro XRF Checker.
Small spot XRF systems are high performance machines for
performing XRF analysis in a region as small as 100 microns in
diameter. To get the most performance out of your system, the
x-ray beam must be carefully aligned to ensure that the correct
area of your sample is being analyzed. Until now there was no
simple and effective way to do this. That is why we designed the
Micro XRF Checker. The Micro XRF Checker is a precision flat
ground copper disk, 1 3/16" diameter x 1/8" thick. On its
surface are two high precision Molybdenum plates with 100 and
150 micron diameter openings, for fine and coarse alignment. You
place the Micro XRF Checker on the sample tray and align the
system by locating the x-ray beam in the opening in either of
the molybdenum plates. Since the copper substrate is exposed in
the center of each plate, you will ge
