Applications of resistive heating in gas chromatography: A review

• This article critically analyses the developments in resistively heated gas chromatography.
• The advantages and disadvantages of different resistive heating technologies are assessed.
• The applications of resistively heated gas chromatography are thoroughly reviewed.
• The considerations and challenges for the application of resistive heating are critically evaluated.

Gas chromatography is widely applied to separate, identify, and quantify components of samples in a timely manner. Increasing demand for analytical throughput, instrument portability, environmental sustainability, and more economical analysis necessitates the development of new gas chromatography instrumentation. The applications of resistive column heating technologies have been espoused for nearly thirty years and resistively heated gas chromatography has been commercially available for the last ten years. Despite this lengthy period of existence, resistively heated gas chromatography has not been universally adopted. This low rate of adoption may be partially ascribed to the saturation of the market with older convection oven technology, coupled with other analytical challenges such as sampling, injection, detection and data processing occupying research. This article assesses the advantages and applications of resistive heating in gas chromatography and discusses practical considerations associated with adoption of this technology.
