• Flow
sets the flow rate up to 5 ml/min. For the example separation
0.4 ml/min is used. If the back pressure briefly reaches the maximum
pressure setting the flow will be reduced for a few seconds to lower the
pressure but if the pressure continues to be limited in this way an error
condition will be created and the flow will be stopped.
• Solvents
defines the mobile phases that are available and the percentage
proportions pumped on the two channels, A and B. On each channel a
drop-down box allows the selection of a solvent from a list so that the pump
control uses the optimum compressibility settings. This will optimize the
flow characteristics as described in
“How to Configure the Optimum Delay
on page 42. A second text box allows a description of the mobile
phase to be entered. If the solvent selection valve is installed in the pump
then each channel has two solvent options and the correct option for the
method is selected with the radio button to the left of the solvent
description. The pump will form binary mixtures of the selected A and B
