This paper reports on the design and performance of an insulated infrared s
pectro-electrochemical cell that is capable of operation at temperatures ot
her than ambient. The cell is built around a glass chamber that holds elect
rolyte solution and the working and counter electrodes. The front of the ch
amber consists of an o-ring seal joins onto which the cell window is mounte
d. The reference electrode is held in a separate compartment behind a wette
d stopcock and connects to the glass chamber through a capillary tube. The
glass chamber is insulated and secured inside an aluminum jacket. The alumi
num jacket provides support for the glass chamber and brings the cell dimen
sions to those typical of a conventional (Seki et al., Appl. Spectrosc. 39
