The exit of the column is stoppered with glass, wool or maybe a porous plate. When the cellular section passes through, the combination separates into bands. These can then be collected and analysed by way of other procedures.one
The target is for all the compounds to elute in as short a time as is possible, whilst nevertheless enabling for your resolution of personal peaks. Standard columns for ordinary stage separation are filled with alumina or silica. Alkyl, aliphatic or phenyl bonded phases are generally used for reverse period separation.
