High-speed, precise temperature control for gas chromatography columns
A recently granted patent (Publication Number: US11879876B2) discloses a heater integrated gas chromatography (GC) column device designed for efficient separation and analysis of compounds. The device comprises a bobbin made of a metal with high thermal conductivity, an insulating layer with a metal oxide film, a heat generating layer containing carbon nanotubes or a carbon nanotube-metal composite, a metal electrode, and a GC column wound around the bobbin. Additionally, a bonding layer, made of heat-resistant silicone or epoxy resin, is included between the bobbin's outer surface and the GC column to enhance stability.
Furthermore, the patent details various configurations and materials used in the construction of the heater integrated GC column device. These include the selection of metals like copper, magnesium, aluminum, or their alloys for thermal conductivity, anodized metal oxide films for insulation, and specific metals like silver, platinum, or gold in the heat generating layer. The device also allows for the incorporation of temperature sensor devices, such as thermocouples or infrared sensors, on the inner or outer side of the bobbin for precise temperature control during chromatographic analysis. Overall, the patented technology aims to improve the performance and reliability of gas chromatography systems for various analytical applications.
