5 The 711 Liquino in synthesis laboratories
The modes which are most interesting for the use of 711 Liquino in synthe-
sis laboratories are the XDOS and SEQ modes.
If necessary the other modes (PIP, CONT, SMPL, GLP) can be hidden in the
operator dialog of the Liquino. This can be done in the setup menu. Pro-
ceed as follows:
•
Switch the instrument off.
• Press the <CONFIG> key and keep it pressed down.
• Switch the Liquino on again.
• You can now see the first entry in the setup menu ' >keyboar d opt i ons '.
• Press the cursor key <> twice.
• You can now see the first entry in this submenu
' hi de XDOS: no' .
• Now press the cursor key <> and use the <SELECT> key to select
'yes' if you want to hide the corresponding mode which is displayed.
Confirm your entry with <ENTER>.
• When the last entry in this submenu ' hi de GLP' has been confirmed with
the <ENTER> key the Liquino switches automatically to the basic condi-
tion. In order to exit from this dialog you can also press the <QUIT> key
twice.
5.1 The advantages of the 711 Liquino
Flexible dosing
Wherever the reaction control is carried out via the reaction time or the
amount of reagent the Liquino is predestined for dosing in the reagents. The
XDOS mode (Extended Dosing) allows a reagent to be dosed in under con-
trol. The exact observance of the reaction conditions with temperature con-
trol and freely selectable dosing speed is completely guaranteed. Different
set parameters can be selected (see also page 74):
♦ Dosing a set volume within a given period ⇒ XDOS-Type: Vol-
ume&Time
The dosing speed is determined automatically.
Interruption-free dosing is possible with two Dosinos in 'tandem'
operation, see page 74ff.
♦ Dosing a set volume at a defined dosing speed ⇒ XDOS-Type:
Volume&Rate
The dosing period can be protocolled in the result report.
Interruption-free dosing is possible with two Dosinos in 'tandem'
operation, see page 74ff.
♦ Dosing during a set period at a given dosing speed ⇒ XDOS-
Type: Time&Rate
The dosed-in volume can be protocolled in the result report.
Interruption-free dosing is possible with two Dosinos in 'tandem'
operation, see page 74ff.
♦ With temperature control (lower limit and/or upper limit) during
dosing the reaction can be deliberately controlled by interrupting
the dosing process. If one of the temperature limits is infringed a
particular action can be programmed, e.g. interruption of the dosing
