Operation
Figure 5-11. The realtime digestion information display
While performing the digestion, the Titan MPS displays the information gathered
from the DTC™ and DPC™ sensors. This information is displayed in real time
(see cool down). If needed, the digestion can be immediately stopped by pressing
the red
Stop button.
After heating is complete, the vessels must remain in the oven for at least ten
minutes. After this cool-down time, all vessels can be removed and can be placed
under a vent hood or other exhaust system for further cooling. The vessels should
be opened in the hood only after an adequate cooling period. This cool down time
can vary depending on the total heating time and the final target digestion
temperature. The sample temperatures must be well below the boiling point of the
reagents, otherwise the sudden release of pressure upon opening the vessel will
cause rapid boiling of the sample within the vessel and possibly eject some material
through the vent port.
