Operation
Compressed Air Requirements
At least 5 bar (80 psi) of pressure is required, with a flow rate of 1.5 Cubic meters per minute (50 cfm). The maximum pressure to the system
is 7.5 bar (110 psi). When the digestion is complete the system open the primary electronic air valve to rapidly cool the digestion vessels. The
cooling rate is approximately 3.5 minutes from 180 °C to 70 °C for 10 mls of sample. At the same time a baffle in the exhaust tube opens
under software control to ensure the proper air flow for the quantity of air being induced into the cavity.
Always use the preset pressure regulator provided.
The end point cooling temperature is not user definable. It is possible to open the lid after the digestion stops, but
the rack will could still be hot to warm. One may run 6 vessels at the same time or less than 6 by placing them
symmetrically in the rack. Deselect the channels to monitor the temperature on the digestion tab of the software.
Start
1. Connect a
Mini
WAVE
digestion module to a
Mini
WAVE
controller using a USB cable provided.
2. Plug the controller to the appropriate wall receptacle (100-240V).
3. Plug the module into the correct wall receptacle for either 115V or 230V.
4. Power up the controller.
5. Power up the module to start the system. The LED indicator on the front panel will change and then register a number
between 1 and 4. This number represents the module number in Module.
6. Compressed air is connected to the back of the each Module for fast cooling.
Before Digestion
1. Placing rack into cavity
When loading a rack into
Mini
WAVE
cavity, it is necessary to ensure that the rack handle is
aligned with the groove in the cover plate motor. Typically if the rack is placed in the system with
rack position 1 in front the rack will align easily.
If a rack is not placed correctly in the cavity the lid will not close
properly.
2. Top cover closing and locking
The cover plate closes by rotating towards the cavity. Rotate the locking mechanism forward to
lock the lid in place. Two interlocks will be engaged to allow the system to digest samples. The
opening handle should click into place when closed completely. The system will not operate if the
cover is not closed completely.
