3D printed metal columns for capillary liquid chromatography.
نویسندگان
چکیده
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.

A rapid and direct method for immobilizing conventional high performance liquid chromatography (HPLC) packing material inside fritless capillaries has been developed. Due to the simple composition of the entrapment matrix (tetraethoxysilane, alkyltriethoxysilane, ethanol and water), straightforward manufacturing procedure and modest equipment requirement, the method can readily be transferred t...

We have previously demonstrated the potential usefulness of capillary columns coated with a high temperature polarizable phenylmethylsilicone liquid phase in plasma lipid profiling (Kuksis, A., J.J. Myher, and P. Sandra. 1990. J. Chromatogr. 500: 427-441). The present study reports improved operating conditions along with a practical application to the analysis of a series of human plasma sampl...
متن کاملSupercritical fluid chromatography and microbore liquid chromatography for drug analysis.
Supercritical fluid and microbore liquid chromatography offer potential applications for drug analysis. In supercritical fluid chromatography (SFC), the mobile phase is a gas (e.g., carbon dioxide) maintained at its supercritical state--that is, above its critical temperature and pressure, above which it cannot be liquefied even with further increases in applied pressure. The SFC mobile phase h...
