Calibration Materials from Silica Gel and TitaniumMicroanalytical calibration materials can be synthesized from doped silica gel (or doped silica glass) with trace-level chemical precision (within 10 ppm of a target concentration) and acceptable homogeneity. The procedure begins by preparing a dopin.....
