Tips&Tricks has been developed by PSS for LC/GC Europe. Since February 2007 it is published bimonthly in LCGC Europe's The Column.
These Tips&Tricks are designed to support GPC/SEC users of in their daily work providing comprehensive overviews on different aspects of this powerful technique.
Many readers collect these publications and approached us for a collection. This resulted in 5 e-books, each book based on 5-8 different Tips & Tricks publications updated with the latest information, new examples and figures.
Please feel free to contact us to receive a pdf. If you miss a topic and want us to elaborate a topic please propose a topic or submit a problem.
