Presentation of Course certificates
The practical part of the course is run on an instrument in the training room. During the course we run a sample mixture using different column, we run a 0-100% gradient to establish approximate k' conditions, and then optimise the eluent composition for methanol, acetonitrile and THF using the Snyder triangle. We use diode array detection to monitor changes in peak elution order, and Drylab method development software to optimise for temperature, pH, buffer concentration and %B. |
