Metrohm's iColumns are the first IC columns that are equipped with a data chip that stores freely definable data, fixed column data as well as data entered by the MagIC NetTM software. Any relevant information such as column type, standard parameters, maximum pressure, etc. can be called up at any time. Analysis data continuously entered by the MagIC NetTM software guarantees a complete column and GLP-compliant surveillance irrespective of the IC system in which the column is operated. The MagIC NetTM software surveys the critical column data and indicates any infringement of limits.
