Dispenser system for mass spectrometric sample preparations

摘要: The invention relates to the preparation of samples on mass spectrometric sample supports with dispensing liquids, and particularly devices methods clean dispenser. During hundreds samples, solved material may crystallize over time as deposit at capillary tip dispenser, which impedes vertical detachment drop in medium long run. Therefore, frequently cleaning is essential for a robust operation device. proposes automatically dispenser by creating washing fluid, such pure solvent, fully enclosing tip. fluid fed through channel outside central location slightly above size hanging photometrically regulated monitored prevent it from falling off prematurely.
