The X-Checker was the first and remains the only complete calibration aid for SEM/EDS Systems. With boron nitride for those who need a more sensitive monitor of low end performance on thin window and windowless detectors.
The X-Checker was the first and remains the only complete calibration aid for SEM/EDS Systems. In addition to the standard features and boron nitride, there is a fluorine source to test resolution at the fluorine K-alpha peak
The TEM Checker contains 5 manganese disks in a standard grid storage box. The discs are not transparent to the beam but will give you a strong manganese peak to check the resolution of your EDS detector.
