4.2.3. Number of syringes, syringe model and flow units
selection
Once a pump model and a rack model are selected, a syringe model
must be selected among the list of compatible models.
A syringe model (either standard or custom) is considered “compatible”
with a rack model when the rack model can hold syringes with a
capacity equal to or higher than the syringe model’s capacity.
The following information extracted from the selected syringe model will
be considered during the rest of the method edition process:
- Syringe
diameter
- Syringe
capacity
You are able to specify the number of syringes the method will make use
of. This value is validated so that it complies with the maximum number of
mountable syringes on the rack.
Although it is only an informative value (that is, the method execution
will consider that the pump unit has a single syringe), the number of
syringes is very important for the operator to be able to prepare the
pump unit when the method is to be executed.
The flow units list allows you to choose among a list containing all
possible combinations of ml, µl, nl and pl with sec, min, and hr. The default
value for the unit is selected depending on the syringe size:
Syringe size Default flow units
0.5 µl to 50 µl nl / min
>50 µl to 1 ml µl / min
> 1 ml to 5 ml µl / min
> 5 ml to 10 ml ml / min
Greater than 10 ml ml / min
If different flow units are selected, the Flow Evolution Graph (see 4.2.4)
is automatically updated to the new flow units.
The syringe diameter of the selected syringe model (D) and the speed
range of the pump model’s pusher block selected (Smin and Smax) are
considered to determine the flow rate range of the overall method.
These values are automatically calculated and displayed when a syringe
model is selected. These values are formatted depending on how many digits
are accepted by the pump model. Therefore the most suitable unit is
determined to show the most accurate number possible.
