'Plastic backed tlc plates' presentation slideshows

TLC plates (also known as chromatoplates) can be prepared in the lab. Silica gel and alumina are among the most common stationary phases, but others are available as well. Many plates incorporate a compound that fluoresces under short-wave UV (254 nm). The backing of TLC plates is often composed of glass, aluminum, or plastic. Glass plates are chemically inert and best withstand reactive stains and heat, but are brittle and can be complicated to cut.
