Abstract: A nozzle for collecting extracted material for efficiently collecting a solution sprayed, together with gas, from an exit-tube at the outlet of a backpressure control valve in a supercritical fluid chromatograph or a supercritical fluid extraction apparatus. A nozzle 10 is fitted to an end of and is used for collecting in a collection vessel a liquid component in a fluid supplied from the exit-tube. The nozzle 10 comprises a nozzle body 12, an exit-tube hole 18 provided in the nozzle body 10, an opening 14 provided at the lower end of the nozzle body 10, a filter 14 provided above the opening 14 in the nozzle body 10, and an exhaust hole 20 provided in the nozzle body 10 at a position above the filter 16. When the nozzle 10 is fitted, the downstream tip of the exit-tube is inserted through the exit-tube hole 18 and is secured so that the downstream tip of the exit-tube is almost in contact with the filter 14. The fluid discharged from the exit-tube is sprayed into the filter 14.
