Low Temperature ir Cell for Studies Using Anhydrous HF as a Solvent

The ir cell described below was developed to study soluble products formed from the electrolysis of ammonium bifluoride in anhydrous hydrogen fluoride. For these purposes it was necessary that the sample be kept in a liquid state, at atmospheric pressure, both in the sample transfer and during ir analysis. It was also necessary that the materials with which the sample (mainly HF) came in contact during sample transfer and ir analysis be resistant to corrosion. No commercial cells or cells reported in the literature could fulfill these requirements.
