WebThe standards are packaged as aqueous suspensions in 15 milliliter (mL) dropper-tipped bottles. The particle concentrations are optimized for ease of dispersion and colloidal stability. The spheres have a density of 1.05 g/cm3 and an index of refraction of 1.59 @ 589 nm, measured at 25 degrees centigrade. WebMar 30, 2024 · It consists of 25 mm x 25 mm pieces of a silicon wafer with a Si-Ge epilayer. The SRM is certified with respect to the lattice parameter of the Si substrate. SRM 640e is also a renewal; SRM 640, silicon powder, was the first NIST SRM for powder diffraction and has traditionally been very popular.
