Adding a new solvent:
• To add new solvents to the list go to an empty posi-
tion (e.g. no. 11) and press EDIT. The editing display
is now empty. You can create your own names now
using the selection knob. For example: An extrac-
tion is performed with chlorobenzene which does
not belong to the standard list. Type CHLOROBEN-
ZENE as described above and press ACCEPT to
add the name to the solvent list. Chlorobenzene now
appears on position 011 on the solvent list.
Resetting the default list:
It is possible to reset the first 10 entries back to the
default solvent list.
• Move the cursor to position 001. The move up
function button is now replaced by DEFAULT. Press
DEFAULT and confirm the message “Load default
solvent list? First 10 entries replaced”. The first 10
entries are now replaced by the default solvent list.
The following entries (011 – 020) remain untouched.
6.2.3 Preheating the instrument
Preheating the instrument to the temperature of the subsequent extraction procedure is a mandatory
operation as it equilibrates the instrument and hence prevents the cells and cup seals from damage.
! CAUTION
Risk of burns by hot heating block and extraction cells.
• Do not touch hot parts or surfaces
• Do not move the instrument or parts of it when hot
NOTE
Never preheat the instrument when the system is closed. Always equilibrate the instrument with
vacant positions first.
