Even thoughyou use a different technique, you can obtain similar separations, and you can switch easily fromone method to the other. Because of the starting material costs, it is often much faster and lessexpensive to use TLC to develop an HPLC separation method.© Copyright 2004 Alltech Associates, Inc.Contact your Alltech office or distributor for current or local prices.465
