DEVICE AND METHOD FOR PRODUCTION OF AERODYNAMICALLY STABILIZED, ELECTRIFIED MICROSCOPIC JETS FOR TRANSPORTING SAMPLES

摘要

To provide a device for producing aerodynamically stabilized, electrified microscopic jets used for transporting biological or other samples by interaction with a pulsed and focused energy beam.SOLUTION: A production device comprises a transport capillary 3 configured to accommodate a transport liquid 2 and provided with an outlet port 4, and a nozzle 5 disposed concentrically and externally to the transport capillary 3. The nozzle 5 has a discharge port 6. A space between the transport capillary 3 and the nozzle 5 is configured to accommodate a stabilizing gas 9. At least a first electrode 7 for applying a voltage to the transport liquid 2 and a second electrode 8 disposed facing the outlet of the transport liquid capillary 3 and the nozzle 5 are brought into contact with the transport liquid 2 in turn such that the electrodes 7, 8 are subjected to an electrical potential difference V.SELECTED DRAWING: Figure 1
