STATIONARY PHASES The symbol of silica gel is K ( For Kieselgel ), followed by a qualifying number. K5 10-12 µm silica, of pore size 150 Å K6 10-12 µm silica, of pore size 60 Å The High Performance silica is prefixed by the letters HP Hence, HP-K 4-5 µm silica, of pore size 60 Å Reversed Phase Plates, with a bonded alkyl group, are represented as one might expect, by a K followed by the length of alkyl chain. KC2 10-12 µm silica, 60 Å, Ethyl bonded phase. KC8 10-12 µm silica, 60 Å, Octyl bonded phase. KC18 10-12 µm silica, 60 Å, Octadecyl bonded phase. Cellulose layers are denoted by K2. OPTIONS L Preadsorbent layers. This compresses each spot into a narrow horizontal line.hence it is known as Linear-K. Prefix L. D Chanelled Plates. 0.8 mm lanes of clear glass separate each sample channel, preventing crossover. D indicates divisions! F Flourescent indicator. Flourscent plates glow bright green under UV light. Samples which absorb UV at 254 nm are detected due to Flourscent quenching. M Microscope Slide, Plate size 1 x 3 P Preparative layer, having 500 µm or 1000 µm layer for large sample sizes. Using the above letterings it is possible to deduce the designation of any plate required, without the need of memorising numbers. e. g. : PLK5F=K5 silica, featuring a preparative, flourescent plate and the preadsorbent layer. 17
