Diffuse Reflectance IR Accessory

DRIFTS is an in situ technology that provides valuable surface reaction information through tracking signs of adsorption to the field reaction on the catalyst, which is suitable for direct measurements of solid powder samples and surface analysis of materials, is simple, does not need to be pressurized and does not change the original sample pattern. In situ analysis can be performed at different temperatures, pressures and atmospheres.

Two configurations:

1. High temperature low pressure reaction (HVC-DPR), vacuum: 1 x 10^-6Torr, temperature: RT-910 °C (under vacuum), optional dome with high pressure, pressure up to 3.4 MPa.

2. cryogenic reaction cavity (CHC-CHA), pressure range: constant pressure to high vacuum (1 x 10)^–6Torr), temperature range: -150 °C – -600 °C (under vacuum)

Three exits, two routes of gas and a vacuum.

316 L stainless steel, resistant to chemical corrosivity.

High-temperature low pressure reaction cavity (HVC-DPR) may be fitted with inert Silcotek coatings to improve corrosive resistance.

The windows can be replaced.

Available for ultraviolet and infrared drift.

Fits Thermo Fisher (Nicolet), Bruker, etc. for various types of infrared spectrometer hosts.
