Volatile samples and solvents being studied can vaporize and form bubbles in conventional liquid sample cells, especially under the influence of the infrared radiation from the source in a continuous-wave instrument. This will result in the formation of spikes on the spectra. In addition, some analytes are thermally labile and must be protected from warming while the spectrum is recorded. An easily constructed cell cooled with a vortex tube can solve many of these problems, and is in many ways an improvement over commercial devices. In this note, such a cell is described and its application to volatile alternative refrigerants is discussed.Read More
