3.5.4 Loading Pumps
The following types of pumps are available for loading sample to the
injection valve:
•
A stepper motor loading pump (P/N 068561) is standard for an SP1.
(This type of pump is used as a dilution pump, also.)
•
A peristaltic loading pump (P/N 068558) is standard for an SP2.
•
For custom SP configurations, either type of loading pump can be
ordered.
Stepper Motor Loading Pump
A stepper motor pump is available for applications in which the sample is
delivered to a concentrator column installed on the injection valve.
The flow rate can be set to between 0.0 mL/min and 3.0 mL/min (the
default is 3.0 mL/min). Use a flow rate appropriate for delivering sample
to a concentrator column. You can change the flow rate in the
Chromeleon 7 Instrument Configuration Manager on the
Pumps/Motors
page.
Enter the volume of sample to deliver (0.1 mL to 1000.0 mL) and other
pump commands in the Chromeleon 7 instrument method or on the SP
ePanel in Chromeleon 7.
Peristaltic Loading Pump
A peristaltic pump (see Figure 3-7 )
is available for applications in
which the sample is delivered to a
sample loop installed on the
injection valve.
When a peristaltic pump is
installed, a solenoid valve
connector (typically
SV9
) on the
main SP electronics board is
assigned to control the peristaltic
pump (instead of a solenoid valve).
