Below, you can find manuals for a number of our measurement capabilities.  These manuals are very thorough; if you follow them step by step and read carefully, you should not have any problems.  The people who have problems the most are those who accidentally skip steps because they are trying to work too quickly.  If you feel that you have found a mistake or something isn't clear, please contact Michael Koehler at

In "Other Documents," you can find information about our training policy and how to set up an account on the online billing/scheduling software (non-UTK users should contact me at before doing this).  You can also find links to the IUCr round robin on quantitative analysis.  You can download the data and practice your Reitveld refinements.  There is also a link that will tell you the actual amounts of each phase in each sample.

Finally, you can find some good articles on different topics under Recommended Reading.
