Scheme of the VAPONADO system

  1. Sample vial
  2. Blowing tube
  3. Sucking tube
  4. Circulation fan
  5. Heater
  6. Level mesurement
  7. Rack mount
  8. Sample chamber
  9. Touch panel
  10. Condenser
  11. Collected solvent
  12. Cooling medium


The energy for the vaporisation (vaporisation energy) of the solvent of the sample is supplied via the heated gas (N2) current. The temperature of the liquid as well as of the gas is measured by means of the pyrometer 6. The level of the liquid then is deduced from the temperature gradient at the solvent surface.
