DXC: The World's Leading Forum for X-Ray Materials Analysis



Volume 20
Issue 7

Spectroscopy previews products and sessions for attendees to see and participate in at the 54th Annual Denver X-Ray Conference, to be held August 1–5 in Colorado Springs, CO.

In 1951, the University of Denver held perhaps the world's first one-day symposium on the application of X-rays to the study of materials and the importance of X-rays in research. The Annual Conference on Applications of X-ray Analysis, as it was known, grew and continues to flourish as the world's leading forum for scientists working in the field of X-ray materials analysis. The Denver X-ray Conference (DXC) still provides a unique mixture of sessions on training and education, applications, and papers containing details about state-of-the-art techniques and future developments in X-ray analysis. Another important part of the meeting is the presence of leading manufacturers of X-ray equipment who exhibit their most recent offerings and have their technical people available to offer suggestions on how one might use their equipment to solve problems.

As a service to those planning on attending the conference, Spectroscopy presents the following preview of products scheduled to be on display at DXC 2005, as well as an overview of the courses, workshops, and lectures that will be offered during the five-day event.

While every effort has been made to present as comprehensive a listing as possible, this article cannot be considered a complete record of every product scheduled to be shown at the conference.
