LB 9507 Chapter 2: Design of the Lumat
2-13
2.7 Reagent Supply
Lumat is available in different versions:
1. without injectors (with septum for manual injections)
2. with one variable injector
3. with two variable injectors.
Setting the injector volume
For instruments with one or two injectors, you enter the desired
injector or injectors together with their volumes once in the
<INSTRUMENT PARAMETERS> menu. The software uses these
settings when creating protocols and performing measurements.
When creating protocols the settings entered in the instruments
parameter can be changed.
Setting ”0” means the respective injector is disabled and does not
appear in the protocol prompts.
Injector volumes:
25 µL - 300 µL in 5 µL steps
If the user enters the injector volume not within the 5 µL step
range, the system rounds up or off. Values out of the range are
adjusted to the limits (25 µL or 300 µL).
Example:
When entering 43 µL the system rounds up to 45 µL, when
entering 102 µL the system rounds down to 100 µL.
Wash function and selected injectors:
If the wash function is selected in the <REAGENTS> menu, only
the injector lines are filled and washed in the case in which an
injector volume > 0 has been entered in the <INSTRUMENT
PARAMETERS> menu.
This manual describes the version with 2 injectors, since this text
covers all other options. So, if your Lumat does not include an
injector, you can skip all information relating to injectors such as
selecting injectors when creating protocols, injecting during
measurement, etc.
