Beschreibung
Zusammenfassung:	The present invention relates to a device and an arrangement for selective solvent evaporation from a liquid feed, the feed comprising one or more components diluted in at least a first solvent or a solvent blend, comprising:a) a first tubular vessel having a distal end or a channel suitable for the formation of a droplet of a first volume, at an inflow rate r1, at the tip or in the lumen of the tubular vessel, andb) means for subjecting the droplet to a solvent removal step at an evaporation rate r2 to evaporate at least part of the first solvent or solvent blend, to accumulate the components in the feed in the droplet during the evaporation process at an accumulation rate r3, to obtain a concentrated feed volume in a concentrated droplet, wherein the evaporation and/or inflow rates are continuously adjusted to achieve a desired accumulation rate. The invention further relates to a method for selective solvent removal from an analyte mixture obtained in a chromatographic separation process.
