Harrick Scientific's temperature-controlled gas cell, designed for transmission spectroscopy, enables the analysis of gases and gaseous mixtures under static or flow conditions. The cell's beam-conforming design not only reduces its volume but also enhances the interaction between the beam and the sample.
Constructed from 316 stainless steel with a pathlength of 10 cm, this cell can operate at temperatures ranging from ambient to 240 °C. These features make it highly adaptable for evolved gas analysis (EGA) when used in conjunction with thermogravimetric analysis for TGA-EGA-FTIR.
The cell is equipped with a K-type thermocouple and low-voltage heaters, which are integrated to function optimally with the Harrick temperature controller.
The complete setup of Harrick's temperature-controlled gas cell includes a stainless steel transmission gas cell, Viton O-rings, and windows. Mounting hardware, an embedded K-type thermocouple, a low-voltage band heater, one port with a needle valve, another plugged port (1/8 NPT), and mating hardware for the designated UV-VIS or FT-IR spectrometer are also part of the package. Note that windows need to be ordered separately.
Key Features
The Harrick’s temperature-controlled gas cell features the following key characteristics:
- A 10 cm pathlength transmission gas cell.
- Capable of both static and flow-through spectroscopy measurements via two ports.
- It can be heated to 260 °C when equipped with Kalrez O-rings and 200 °C with Viton O-rings.
- Higher temperatures are achievable with metal O-rings.
- Beam-conforming interior design enhances the pathlength-to-volume ratio.
- Cell volume of 17 ml.
- Clear entrance and exit apertures with a 20 mm diameter.
- Constructed from chemically resistant 316 stainless steel.
