Using TLC to Choose an HPLC Column

December 10, 2014 11:55 am | by Fred Rabel, Owner, ChromHELP, LLC, Woodbury, N.J. | Articles | Comments

Because of the high cost of HPLC columns, there are numerous ways to find out which column(s) might best be of use for an intended but new separation. If some of the components are known, then the literature or manufacturers’ websites can be consulted. This might take some time, but the research of others can save both time and money in your own work.
