METHOD AND DEVICE OF PRODUCING AN INTERMITTENT LIQUID JET

摘要

A method of producing an intermittent liquid jet (1) comprises the steps of delivering a liquid (2) through a gas dynamic nozzle (10), which includes an inner tube (11) carrying the liquid (2), an outer tube (12) carrying a focussing sheath gas (3), an exit channel (13) and an exit aperture (14), injecting a stream of the liquid (2) into the exit channel (13), wherein the liquid (2) is enclosed by the focussing sheath gas (3) in the exit channel (13), controlling emission of the liquid (2) from the inner tube (11) into the exit channel (13) to produce a periodic, linear intermittent liquid jet (1) including spurts of linear continuous jet sections (4) separated by liquid-free gaps, and output of the intermittent liquid jet through the exit aperture (14). Furthermore, a method of scattering measurements on samples in a liquid using the method of producing an intermittent liquid jet (1) and an injector device (100) for producing an intermittent liquid jet (1) are described.
