3D printed metal micro columns for Thermal Gradient Gas Chromatography
Gas chromatography (GC) is a method for separating gasses and volatile compounds for measurement by running them through a heated capillary. It has many uses in various industries such as gas, security, health, and food safety. Power requirements and the size of modern gas chromatography systems limit the mobility of these devices as well as their reach. Research suggests that applying a thermal gradient across the capillary allows for significant length reductions. While many research groups have looked into applying micro GC technologies to silicon with standard cleanroom fabrication techniques, our group is looking into fabricating this device using a metal 3D printer. Advantages of micro GC systems printed in stainless steel or copper are thermal conductivity and robustness of the device.
