Abstract
A reticulated annular capillary GC column is disclosed including a capillary wall, a core disposed within the capillary wall, an annulus disposed between the capillary wall and the core, and vanes disposed in the annulus. The vanes extend along the length of the capillary wall for less than the length of the capillary wall. The vanes define a reticulated flow path through the annulus. The vanes structurally support the core within the capillary wall. A method for forming the reticulated annular capillary GC column is disclosed including forming a preform master pattern by an additive manufacturing technique, the preform master pattern including a preform wall, a preform core, a preform annulus disposed between the preform wall and the preform core, and struts disposed in the preform annulus. A preform is cast from the preform master pattern, and the preform is drawn down, forming the reticulated annular capillary GC column.
