Aluminum scanning electron micrographs

Changes in wettability are unlikely, since the base polymer of Elastomers A, B, C, CC, D, DD, and E has a contact angle of <1.5 to untreated aluminum. Scanning electron micrograph (18,000 x) shows no surface change resulting from acetic acid treatment.

A third type of protective outer coating, stainless steel, for fused silica offers an alternative to aluminum-clad fused silica for elevated column temperatures. This technology is the inverse of that for polyimide-clad fused-silica capillary where a layer of fused silica is deposited on the inner surface of a stainless capillary. In Figure 3.19 scanning electron micrographs are displayed to compare the rough surface of stainless steel with the smooth surface of untreated fused silica and the surface of stainless steel after a micron meter layer of deactivated fused silica...
