Transmission sample holders

TRANSMISSION SAMPLE HOLDER


Transmission sample holders are excellent for quick overview measurements as well as Rietveld quality data collections. Powdered substances of every origin can be measured including polymer fibers or foils.
Even with minuscule sample amounts finest layers can be prepared on STOE’s zero scattering foils, making this technique preferable for transmission measurements of highly absorbing materials.

CHARACTERISTICS

  • Easy and clean preparation of samples on
    zero scattering foils
  • Convenient loading of samples including exposure mask with variable sizes
  • Sample displacement due to variable sample thicknesses can be corrected by a micrometer screw
  • Sample rotation in a high precision ball-bearing to avoid reflex broadening and result in low noise

AVAILABLE FOR: STADI P / MP / COMBI

TRANSMISSION SAMPLE CHANGER

The transmission sample changer is set up as an additional pre-aligned unit and controlled via the WinXPOW software. Users benefit from fast sample throughput, proven reliability and high-quality data sets. Each file is carrying its unique identifier accessible through the flexible WinXPOW file management system, while batches can also be controlled through an XML sheet.

  • Capacity of up to 30 samples
  • Loaded and Unloaded simply by stacking
  • Controlled by STOE´s Software Package WinXPOW

AVAILABLE FOR: STADI P / MP

Combinatorial SAMPLE CHANGER

The motorized x-y stage of the combinatorial analysis sample holder enables rapid measurements, even with minimal sample material, including liquids in transmission mode. Due to its layout, combinatorial and high throughput analyses can easily be conducted.

  • Easily exchangeable inserts for up to 96 samples
  • Other inserts possible due to variable x-y grid
  • Height adjustment by micrometer screw
  • Software driven position control, batch mode possible

AVAILABLE FOR: STADI P / MP / COMBI

Capillary sample holders

Capillary sample holder

Capillary measurements minimize preferred orientationand resulting in narrow FWHM and symmetric profiles leading to accurate intensities for structure solution and Rietveld refinement. The preparation in sealed capillaries is suitable for air sensitive and hygroscopic materials. Moreover, this setup is compatible with low temperature attachments.

CHARACTERISTICS

  • Glass capillaries between 0.1 and 2.0 mm diameter
  • A precise goniometer head, aligned by video CCD control, guarantees coincidence of capillary and diffractometer axis

AVAILABLE FOR: STADI P / MP / COMBI

capillary sample changer

Automated, high throughput measurements of, e.g., air or moisture sensitive samples are enabled by the capillary sample changer on which three guide bushes for sample insertion make further alignment unnecessary. The position of the capillaries in the X-ray beam and their exposure time are controlled by STOE’s WinXPOW software.

  • Capacity of up to 10 capillaries
  • Additional height adjustment for optimized sample position in the beam
  • No capillary alignment necessary

AVAILABLE FOR: STADI P / MP

PERMANENTly ALIGNED CAPILLARY SAMPLE HOLDER

Applications

A permanently aligned capillary stage speeds up the measurement preparation process and is suitable for qualitative and quantitative phase analysis. The data acquisition itself can be sped up by using a fast Mythen 2K/3K/4K detector.

  • Auto-alignment due to three guide bushes
  • Easiest capillary exchange
  • Sample rotation for excellent statistics
  • Height adjustment for an optimal sample position in the X-ray beam
  • Capillaries between 0.1 and 1.1 mm

AVAILABLE FOR: STADI P / MP / COMBI

GANDOLFI SAMPLE HOLDER

Applications

The Gandolfi sample holder is specifically designed to minimize preferred orientation effects in a measurement.

  • High-precision goniometer head
  • 45° phi axis
  • Permanent rotation

AVAILABLE FOR: STADI P / MP / COMBI

Reflection sample holders

REFLECTION SAMPLE HOLDER


The reflection mode has to be applied in all cases where the transmission or the capillary techniques cannot be used, e.g. for measurements of bulk materials, liquids or thin layers.

CHARACTERISTICS

  • Precise height adjustment of the sample using a reference blade
  • Zero background sample inserts with or without cavity

AVAILABLE FOR: STADI P / MP

REFLECTION SAMPLE CHANGER

The reflection sample changer is set up as an additional unit, where sample heights can be individually adjusted. Users benefit from fast sample throughput, proven reliability and high-quality data sets. Each file is carrying its unique identifier accessible through the flexible WinXPOW file management system.

  • Capacity of up to 12 samples
  • Easy height adjustment for each sample (max. thickness 20 mm)
  • Controlled by STOE’s Software Package WinXPOW

AVAILABLE FOR: STADI P / MP

REFLECTOMETRY SAMPLE HOLDER

Applications

Sample tilting and precession have a large impact on reflectometry data quality, thus, STOE’s tilt and precession free reflectometry sample holder has been specifically designed for accurate alignment for, e.g., experiments to determine film thickness, composition and interface roughness, standard powder diffractometry or grazing incidence experiments for phase analysis of thin films.

  • Reference blade for reproducible height adjustment
  • Micrometer-controlled sample alignment with digital sample position display
  • Manual tilt correction possible
  • Sample spinning for wide-angle X-ray diffraction

AVAILABLE FOR: STADI P / MP

MULTI-PURPOSE ANALYZER STAGE

Applications

Powder diffraction can also be employed to align larger single crystalline samples according to their crystallographic axes. Sample alignment is necessary for certain physical property measurements or prior to grinding and cutting.

  • Standard IUCr goniometer head mount
  • Motorized and PC-controlled x and y translation ± 10 mm with a resolution of 5 µm
  • Motorized and PC-controlled rotation
  • Manual micrometer-controlled z-translation (0-50 mm) for the alignment of a crystal surface or a sample array to the reference blade

AVAILABLE FOR: STADI P / MP / COMBI

HIGH TEMPERATURE ATTACHMENTS

STOE HT1

The STOE STADI P and STADI MP are the ideal equipment for the observation and evaluation of phase transitions in non-ambient environments. Therefore STOE has developed the capillary furnace series for powder investigations at high temperatures:

  • The basic version from RT to 1223 K (950 °C)
  • The extended T version from RT to 1773 K (1500 °C)
  • The furnace with low temperature option for a range from 223 K (–50 °C) to 1223 K (950 °C)
  • 130° exit window

Every STOE furnace is delivered with a temperature controller containing power supply, flow meter for cooling water control and interface to the PC. All three versions provide sample spinning to avoid effects from preferred orientation and offer a temperature stability better than ± 1 K in the whole range. The temperature programs are easily set-up and executed and the STOE furnaces can be mounted on every vertical transmission diffractometer. Heating elements are available for capillaries with diameters from 0.2 to 1.0 mm.

AVAILABLE FOR: STADI P / MP

STOE IN-SITU HT2

The new STOE IN-SITU 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 1823 K (1550 °C) with the possibility of using extremely small sample volumina and gas flows. To reduce effects of preferred orientation the furnace offers sample oscillation and it fits on every vertically mounted STOE transmission diffractometer.

  • Temperature range from RT to 1823 K (1550°C)
  • Gas flow between 0.01 and 0.1 l/min
  • Sample volume from 5 to 20 mm3
  • For Mo or Ag Kα1-radiation
  • Sapphire or glass capillaries

THIRD PARTY NON-AMBIENT SAMPLE STAGES

In addition to our own systems we regularly install third party non-ambient environments. For example high temperature chambers in reflection geometry by Anton Paar or cooling devices by Oxford Cryosystems. If you are interested in another non-ambient sample stage, we are open to implementing it in our machines.

Battery Sample holders

In-operando coin cell holder

The STOE coin cell sample holder was conceptualized based on a patent by Herklotz et al. [1] and was implemented to facilitate the connection to a potentiostat and offer charge-discharge measurements during a diffraction experiment on a STOE transmission diffractometer. In-operando analyses of structural changes during battery cycling are a convenient form of studying new electrode materials.
