Coiled planar capillary chromatography columns (0.9 mm I.D. × 60 cm <i>L</i>) were 3D printed in stainless steel (316L), and titanium (Ti–6Al–4V) alloys (external dimensions of ~5 × 30 × 58 mm), and either slurry packed with various sized reversed-phase octadecylsilica particles, or filled with an <i>in situ</i> prepared methacrylate based monolith. Coiled printed columns were coupled directly with 30 × 30 mm Peltier thermoelectric direct contact heater/cooler modules. Preliminary results show the potential of using such 3D printed columns in future portable chromatographic devices.
