HIGTHROUGHPUT NEW X-RAY POWDER DIFFRACTION
27 September 2005 - CCLRC Daresbury Laboratory

Following discussions with STOE, Darmstadt 's prestige designer of scientific instruments, DARTS commissioned a bespoke automatic sample changer for use on the high flux powder diffraction station 9.1. Customers working in speciality chemicals and pharmaceuticals will particularly benefit from the high throughput for phase or polymorph identification, structure analysis and combinatorial chemistry studies, where the high intensity of synchrotron radiation is essential.

The sample changer has been developed for automated measurements of up to 10 samples loaded in capillaries. Using the sample changer couldn't be easier and there is no special training required. The thin-walled glass capillaries are inserted into the guide bushes, eliminating alignment of the goniometer head. Height adjustment to optimise the amount of sample material in the beam is made at the outset and subsequent translations ensure each sample is aligned correctly. The maximum scan range is 0-90° in 2Θ.

DARTS customers using the automatic sample changer will immediately benefit from increased efficiency. Running continuous measurements on a large number of samples, possibly overnight, will eliminate long working hours by those who are working to tight deadlines. The 10 samples can be loaded at the beginning of the day and results collected 24 hours later! For those customers who prefer to send in their samples for analysis and benefit from savings in manpower and travel, DARTS staff are, of course, available to carry out the work on their behalf.

The automatic sample changer will be available to DARTS customers at the end of 2005. If you have any enquiries regarding technical specifications or indeed, use of the automatic sample chamber, please contact darts@dl.ac.uk

About: CCLRC Daresbury Laboratory
DARTS is a unique service offering solutions to materials characterisation problems that are unattainable in the conventional laboratory. This is possible because it makes use of the Synchrotron Radiation Source (SRS). Advantages of using the SRS include:

• The ability to study small or weakly diffracting samples. Improved resolution, enabling structures intractable in the home laboratory to be solved.

• The ability to select the optimum wavelength for a particular application.

• Additional specialised techniques only possible using synchrotron radiation can be exploited.

The DARTS team's ability to access and combine a range of complementary techniques provides information to help manufacturers control processing conditions and modify manufacturing techniques to improve a wide range of products. Even the everyday crisp packet has benefited from DARTS leading edge technology.

Applications can cover materials from agrochemicals, pigments, polypeptides, microporous materials, organometallics, catalyst materials, minerals and samples from processing plants.
