MAC has a wide range of sets of standards available for immediate delivery, from stock.  MAC only purchase reference samples from leading suppliers to ensure consistent high quality., the samples are fitted into blanks in our own modem factory; diamond polished to a 0.25 micron finish and carbon coated. Then every single reference standard is tested with our own SEM & Analysis Equipment.  All the standards supplied come with a certificate of analysis and a large number of the standards are traceable to a national institution as a standard reference material (SRM).
It is also Possible to make your own set of standards (see materials lists)
