A temperature-programmable, disposable gas chromatography (GC) device was designed and constructed for field application and screening. The modular GC device can be readily interfaced to portable analyzers and/or detectors, and it can be easily replaced. The GC module can be thought of as a replacement of a standard laboratory GC system. It is believed that the GC module is the first of its kind where GC column temperature is programmable and consumes 8 W during heating (45{degrees}C/max. heating rates). The present GC device is 9{times}6.5{times}4cm, weighs 160 grams, has conventional temperature-programming capabilities, consumes a total of 15 W of electrical power during a typical GC analysis, and has relatively rapid cooling rates (time constant is 36 seconds) to reduce downtime. This paper also presents some of the features, design, and engineering aspects applied to the construction of a field-deployable GC device that can be easily fit in the palm of a hand. The modular GC showed relatively rapid separation (seconds) of chemical compounds while retaining the required fieldable properties.
