STOE STADI P COMBI

Diffractometer for combinatorial and high-throughput analysis

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.

Features

  • High-throughput analysis for phase identification and similarity checks
  • 96-fold sample stage – user definable x/y grid
  • Pure Kα1 radiation using Co, Cu, Mo or Ag radiation
  • Transmission geometry

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.

  • goniometer heads for capillaries
  • for Debye-Scherrer or Gandolfi mode
  • sample holders and sample changers for Transmission and Bragg-Brentano geometry
  • a 10fold 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
  • Easily adaptable for transmission samples
  • 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.
