RETICULATED ANNULAR CAPILLARY GAS CHROMATOGRAPHY COLUMN AND METHOD FOR FORMING RETICULATED ANNULAR CAPILLARY GAS CHROMATOGRAPHY COLUMN

摘要

Disclose a kind of netted ring shaped capillary GC columns (100), it includes capillary wall (102), core (104) in capillary wall is set, ring (106) between the capillary wall and the core is set, and the blade (108) being arranged in ring. Blade extends less than the length of capillary wall along the length (110) of capillary wall. Blade limits the netted flow path across ring. Core of the blade in structural support capillary wall. Disclose a kind of method for being used to form netted ring shaped capillary GC columns, it includes forming prefabricated component master mold by increases material manufacturing technology, the prefabricated component master mold includes prefabricated component wall, prefabricated component core, prefabricated component ring between prefabricated component wall and prefabricated component core, and the pillar being arranged in prefabricated component ring are set. By prefabricated component master mold casting prefabricated component, and prefabricated component is pulled down, forms netted ring shaped capillary GC columns.
