Polished SRM612 in T100-52 mount
NIST silicate glass SRM 612 is widely used as a reference material for various microanalytical techniques, and has been nominally doped with 61 trace elements at the 50 ppm level. A discussion of this SRM, and other glasses of this series, can be found in Hinton (1999).
