The advantages of monosized chromatographic supports are as follows a uniform column packing, uniform flow velocity profile, low back pressure, high resolution, and high-speed separation compared with the materials of broad size distribution. Optical micrographs of 20-p,m monosized macroporous particles and a commercial chromatography resin of size 12-28 p,m are shown in Fig. 1.4. There is a clear difference in the size distribution between the monodispersed particles and the traditional column material (87).

Fig. 20. Optical micrograph, lOOOx, taken with a metalographic microscope of CdTe deposits. The good deposit is on the left, and was produced using reasonable potentials. The bad deposit is on the right, and was produced with a program where the potential for Te was excessively negative, leading to roughening of the deposit, and what is referred to here as sand, due to its appearance in the microscope.
