STOE STADI MP

The unique multipurpose powder diffractometer offering three geometries

STOE has developed a new type of diffractometer which is more flexible than any existing system without any loss in performance. The STADI MP combines the two most common diffractometer configurations: Transmission/Debye-Scherrer and Bragg-Brentano geometry with a set-up for micro-diffraction.

Features

  • Various state of the art detectors
  • High and low temperature attachements
  • Transmission / Debye-Scherrer, High Flux and Bragg-Brentano mode
  • Geometry selection by sliding tube housing
  • No realignment after changing geometries
  • All geometries running with pure Co, Cu, Mo or Ag Kα1 radiation

Detectors DECTRIS

DECTRIS MYTHEN 1K
The DECTRIS MYTHEN 1K strip detector has been implemented in 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 > 1×106 it is superior to classical X-ray detectors.

MULTI-MYTHEN 2K/3K/4K – IF ONE MYTHEN IS NOT FAST ENOUGH
Ideal for capillary measurements, all STOE furnaces and the INSITU HT2 heating and reaction chamber.

Detectors STOE

STOE’s IP-PSD

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.

Sample holders

Various sample holders are available for the STOE Stadi P series.

  • sample holders for capillaries (Debye-Scherrer), flat transmission samples, reflection samples (Bragg-Brentano) and for Gandolfi mode
  • 30-fold changer for transmission samples, 12-fold changer for reflection samples and 10-fold capillary changer
  • the x/y-stage for well plates in transmission mode
  • multipurpose sample stage
High- and low-temperature attachments

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:

  • 0.65.1 room temperature to 950°C
  • 0.65.3 room temperature to 1500°C
  • 0.65.LT from – 50°C to 950°C
  • Continuous sample spinning leading to effective particle randomization
  • Well-defined sample position yielding reasonable lattice constants
  • Fully integrated PC-based data collection
  • Quick exchange against other sample stages and easy alignment
  • Supporting all capillary diameters between 0.2 and 1 mm
  • Excellent diagrams obtainable from very small sample amounts
STOE INSITU HT2

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.
