4. Operating procedures
Operating method
(6) You select temperature control for inlet or outlet
temperature using SWITCHING. When you want to control
temperature by the outlet temperature, select inlet
temperature at the start of operation switch to outlet
temperature once the temperature has stabilized. When
operation of N
2
IN has finished and the screen has
changed, set a temperature on the inlet temperature
controller and turn the heater ON.
* Setting ranges will differ among temperature controllers.
Outlet temperature setting range:0 to 60
℃
Inlet temperature setting range:0 to 150
℃
(7) When the inlet and outlet temperatures have risen to or
above the temperature you want and the cooling trap
temperature has dropped is stable, set the spray pressure,
turn the pump FWD switch ON, and send solvent liquid.
Also, open the ball vale above the collecting flask to start
recovering solvent.
(8) Readjust dry air amount, spray pressure, and liquid sending
speed so that the inlet and the outlet temperature will be
stable at the temperatures you want.

・
Influences below are of specific settings on the outlet
temperature when the inlet temperature is constant.
Sent specimen liquid amount
→small
:
outlet temperature →high
Circulation air amount
→large
:
outlet temperature →high
Specimen density (external factor)
→high
:
outlet temperature→high
・
Drops of sprayed liquid will become fine at a higher
spray pressure.
・
When specimen is switched from solvent liquid to
the specimen actually used, the outlet temperature
will be slightly higher because of non-evaporated
component (solid component).
