The planchets are made of Beryllium with a 99% or better purity and any of the possible
impurities will not exceed 0.08% . In fact most of the possible impurities are well
below 0.01%. Using proper cleaning and safety procedures the planchets can be used
again. Available in three sizes to fit the most widely used specimen mounts. Surface
finish is smooth: 1.6µm or less and is perfectly suitable for many applications.

| Calcium | < 0.0100 | | Molybdenum | < 0.0005 |
| Carbon | 0.020 | | Nickel | 0.0200 |
| Chromium | < 0.0100 | | Nitrogen | < 0.0300 |
| Cobalt | < 0.0010 | | Silicon | 0.0300 |
| Copper | 0.0060 | | Silver | < 0.0003 |
| Iron | 0.0800 | | | |
Warning: Cleaning and handling of Beryllium must be done in such a way that it does
not generate particulates which are toxic when inhaled.
An alternative for beryllium planchets could be
graphite planchets
which also gives a low background and virtually no characteristic peaks other than carbon.
