Cutting-Edge Temperature Controlled Gas Cell by Harrick Scientific

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 pathlengthof 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.
