Sigma product S9258 has the same properties as Merck Silica product 15111. Either product number describes the same silica product.
What does "suitable for column chromatography" mean in the listing for silica gel Product No. S9258?
The combination of particle size range, pore size, and surface area has been found to be suitable for compound separations in a variety of flash and column chromatography applications.
Is any pretreatment required before using Product No. S9258?
Some silica applications will work best if the silica is dried at 150-160 °C to remove excess water.  This process is sometimes called activation and may improve separation of compounds.  Most silicas contain 10-20% water unless carefully handled to minimize water uptake over time.
