Abstract
Gas chromatography apparatuses are provided that can include a housing configured to substantially envelop the column within the compartment. Analytical instruments are provided that can include at least one chromatography column compartment having a volume of the less than 100 mL. Analytical methods are provided that can include increasing the temperature of a chromatography column at a rate of about 60° C./minute using less than about 40 W. Methods are also provided that include providing at least one gas chromatography column compartment configured to substantially envelop a gas chromatography column and performing analysis with the one compartment in the first operable position and/or transitioning portions to the second operable position to allow access to the one compartment. Production processes are provided that can include forming a first trench within the first surface of a substrate and/or aligning the first substrate with a second substrate to define at least one compartment between the first and second substrates.
