ABSTRACT:
For nebulizing sample liquid for spectroscopical purposes a liquid to be nebulized is pressurized to a minimum pressure of 30 bar through a high-pressure pump formed as a separate unit, and is nebulized through a nozzle having a smallest flow aperture of less than 5.multidot.10.sup.-9 m.sup.2. The high-pressure pump and the nozzle are interconnected through conduits. In one embodiment the pump takes in pure solvent. The sample is taken in on the high-pressure side through a loop, which is arranged to be connected between pump and nozzle.
