YMC America, Inc SIL guard 120A 5um 10x3mm
The high-purity silica found in YMC-Pack SIL columns provides virtually complete sample recovery The absence of silica impurities reduces non-specific sample adsorption and the totally porous nature of the silica provides high sample loading The elevated chemical purity of YMC silica results in a particle structure exhibiting high mechanical strength YMC-Pack SIL is suitable for separation of fat-soluble compounds using non-polar mobile phases as well as the separation of positional isomers that are difficult to separate in reversed-phase mode SIL-06 (60 pore size) has greater adsorption properties than SIL (120 pore size) due to its larger surface area and is generally useful for separating natural products with low molecular weight
