Development of an ultra-micro sample injector for gas chromatography using an ink-jet microchip.
An ultra-micro sample injector for gas chromatography (GC) was developed. An ink-jet microchip, originally used for industrial recorder, was modified at the edge near to an orifice, and fixed into the GC. In order to evaluate the characteristics of this injector, a sample injector and a thermal conductive detector (TCD) were connected directly, while water was used as the test sample. The volum...
متن کاملThe Dual - Piston Jet Injector and the Viability of Drug Delivery
Drug delivery through jet-injection opens the doors to very rapid drug dispersion by eliminating the need for needle sterilization. With this comes the need for a continuous flow of fluids from a large reservoir, currently not available to the single-piston drug delivery systems. A two-piston system in a jet injector enables the use of a cyclic motion of pistons to drive the injected fluids, as...
متن کاملThe Development of Injector Units for Jet-Lift Engine Simulation on Low-Speed-Tunnel Models
Small-scale injector units have been developed for providing the engine nacelles of V/STOL models, with both intake and exit flows. The primary energy supply was cold compressed air at pressure ratios up to 4:1. With the chosen injector arrangement, a stable and uniform exit velocity distribution was achieved, with a mean velocity of nearly 650 ft/sec, and almost 50 per cent of the jet efflux d...
