Pretreatment
This option enables several pretreatment operations of pumps and valves
before injection and starting the data acquisition. For setting up see
below on page 89.
Solvent Type… (S 1050 / P2.1L only)
Select in the Solvent Type menu the used solvent for a proper
compression and flow correction. Note that for an LPG pump only one
solvent type can be selected.

Pump Program
Accordingly the spreadsheet for the pump program is displayed. Up to
four columns for the composition will be displayed. Additionally, for
pumps with digital outputs, the option for digital outs is given in a
separate column. The spreadsheets of the S 100 / 10P/20P/P2.1S/P4.1S,
K-120, K-501, and the Kontron pumps do not include this column.

isocratic
For all time programs, the minimum time step between two lines is
0.02 min, except for the preparative pumps P2.1L / 1800; here the
minimum time step is 0.06 min. For the pump P2.1L in isobar mode,
the smallest time step is 0.25 minutes.
Use the spreadsheet in the pump setup view to enter your time (gradient)
program. The number of columns shown depends on the defined system
(isocratic, LPG, or HPG) and the number of included components.
