TestYourColumn.org is a new tool that enables you to quickly and easily measure the selectivity of your HPLC column using LC-MS.

To use it, you simply run a standard test mixture on your reversed-phase HPLC column and load the LC-MS data file into the LC-MS Column Tester application. The application automatically extracts the retention times of the standards and calculates your column selectivity parameters for you.

Try it out! Just follow the step-by-step instructions at www.testyourcolumn.org.
