Abstract

Coiled planar capillary chromatography columns (0.9 mm I.D. × 60 cm L) 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 in situ 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.

摘要

螺旋平面毛细管色谱柱（内径0.9毫米×长度60厘米）采用不锈钢（316L）和钛合金（Ti-6Al-4V）通过3D打印制成（外部尺寸约为5×30×58毫米），并使用各种尺寸的反相十八烷基硅胶颗粒进行匀浆填充，或填充原位制备的基于甲基丙烯酸酯的整体柱。螺旋打印柱直接与30×30毫米的珀耳帖热电直接接触加热器/冷却器模块相连。初步结果表明，这种3D打印柱在未来便携式色谱设备中有应用潜力。
