High temperature, high pressure FTIR
Specac’s High Temperature High Pressure Cell (HTHP) Accessory is a multipurpose cell for the FTIR analysis of solid samples in transmission, decomposition, or specular reflectance modes. Sample temperatures up to 800ºC can be obtained and the cell can operate at pressures from vacuum (0.1 torr) to 1000 psi for in-situ reaction studies.
Transmission spectroscopy with sample discs or cups
The standard HTHP Cell can be used for transmission analysis of 13 mm diameter discs, or for decomposition spectral analysis of gases evolved from a solid sample held in a sample cup just below the beam height.
Spectral reflectance measurements are facilitated by an alternative baseplate configuration with transfer optics, and with one of the standard window housings replaced with an angled window housing assembly. The parts required for this conversion are available as an upgrade kit , or provided as standard if the HTHP Cell is been ordered as the advanced version (GS 05855). Gas connections on the cell are provided for gas flow or purging purposes.
Corrosion resistant, vacuum compatible
The HTHP Cell is manufactured predominantly from corrosion resistant and vacuum compatible materials. ZnSe windows and silicone seals are used as standard, but other window materials and seals can also be provided. Temperature control of the accessory is provided by a dedicated power controller.
