摘要： In a microprocessor-controlled evaporation/concentration system, a plurality of sample solutions are automatically successively delivered to an evaporation chamber (11,27) for evaporation and/or concentration. Each sample solution is evaporated in successively delivered slug components whereby each slug is delivered for temporary storage into one of two storage loops (22, 23) while the previous slug is transferred from the other loop to the evaporation chamber. The evaporation chamber (27) has a ceramic bottom wall (29) with known thermal transfer properties. The underside of the bottom wall is maintained at a microprocessor-determined constant evaporation temperature by an electrical resistance heater (30) and proportional temperature controller (31). Pressure in the chamber is maintained substantially on the vapor pressure versus temperature curve of the sample solution, thereby assuring a known evaporation rate. Valving (V14) controlled by the microprocessor permits automatic addition of diluent to the chamber to form a prepared solution of known concentration with the residue from the evaporated sample. The prepared sample is then automatically transferred to one of multiple storage vials (41) which are brought into successive registration with a syringe needle assembly (44) by means of a rotatable vial storage tray (40). The microprocessor (15) automatically cleanses the entire flow system with cleansing solution and/or purging gas after each sample has been evaporated/concentrated.
