Technical Support

Dionex's goal is to provide you with solutions to your analytical challenges rather than just selling you an instrument. To meet that goal, we offer a complete line of service products, including validation products, installation and warranty service, and comprehensive service agreements. In addition, training courses are available to help you get the most from your instrumentation.
