Based on the well known STADI P, STOE has developed a new powder diffractometer for high-throughput and combinatorial measurements in transmission geometry. With its newly designed sample stage providing a variable x,y grid for various slide-in sample holders, eg. for up to 96 different samples, the STADI P COMBI offers highest efficiency combined with all the advantages of the STADI P system.
The STOE IP-PSD is an on-line system with a readout time of about 15 sec for a full range of 140°. The Imaging Plate technology allows short exposure times to give excellent counting statistics even for weak reflections. The combination of the IP-PSD with STOE´s stages, sample changer or various high- and low-temperature systems is an explicit idea of its use.
DECTRIS MYTHEN 1K
The DECTRIS MYTHEN 1K strip detector has been implemented to the STOE powder diffraction systems. It features a range of 6 to 25° in 2Θ depending on the distance between sample and detector. With its high dynamic range of > 2×105 it is superior to classical X-ray detectors.
MULTI-MYTHEN 2K/3K – IF ONE MYTHEN IS NOT FAST ENOUGH
Ideal for capillary measurements, all STOE furnaces and the INSITU HT2 heating and reaction chamber.
Various sample holders are available for the STOE Stadi P series.
With its family of capillary furnaces STOE provides one of the most precise and temperature stable high temperature attachments for the STADI P series and for synchrotron facilities.
Temperature ranges are from:
The new STOE INSITU HT2 high temperature reaction chamber has been designed to study solid state and solid state – gas reactions in capillaries in a temperature range between RT and 1600˚C on a vertically mounted transmission diffractometer, e.g. the STOE STADI P or STADI MP.
The high temperature chamber consists of a cylindrical double walled, water cooled body with an entrance collimator for the primary beam and an exit window with 90° opening for the diffracted X-rays (covered with Kapton® foil). The heating element consists of a coiled graphite
rod, which is clamped between the lid and base plate and contacted by a thermocouple
directly. To reduce effects of preferred orientation the sample can be oscillated by a motor.
The STOE IN SITU HT2 is fully computer-controlled in the newest WinXPow software version.
