ATR Crystals
-
SplitPea and Meridian Mounted Crystals
Ambient Heatable
Applications
- Excellent for changing the penetration depth into the sample.
- Allows ATR data acquisition over a variety of spectral ranges and sampling conditions.
- Monitor changes in materials as a function of temperature.
- Ideal for examining micro-chemical reactions and reaction kinetics.
Features
- Inert Si and Diamond ATR crystals available.
- Ge and Si ATR crystals feature a small sampling volume with a low penetration depth and a 250µm diameter sampling area.
- ZnS, ZnSe, and Diamond ATR crystals feature a larger sampling volume with a deeper penetration depth and a 500µm diameter sampling area.
- Chemically resistant holder.
- Compatible with the SplitPea™ and Meridian™.
- Temperature Controlled Cell includes
- Si, Diamond or Ge ATR hemispherical crystals available.
- Operable up to 200ºC for Si, ZnSe and diamond or 100ºC for Ge.
- Includes K-type thermocouple and 24V heater.
- Leak-free design.
- Compatible with the Temperature Controller.
