Function
Specifies the time (in
minutes) for the solvent
delivery system to reach the
maximum system flow rate.
This limits the rate of change
of the flow rate to protect the
column from potentially
damaging sudden changes
in pressure.
This flow ramp is used for all
applications of the
separation method and
overrides any flow rate
time-based changes defined
within a gradient table.
Displays the Gradient Table
screen, which allows you to
build a gradient table.
Displays the Degasser
screen which allows you to
set the Degasser Mode. See
"Degassing solvents" on
page 57.
On Degasser Error:
Specifies that an alarm
response occurs when an
in-line vacuum degasser
fault is detected. The in-line
degasser is disabled on any
fault regardless of the alarm
setting you select. Waters
recommends that you
enable either the "Stop
Function" or "Stop Flow"
alarm setting.
Displays the Solvents dialog
box, which allows you to
add, remove, or change the
names of solvents used in
methods.
Use the Add, Remove, and
Change screen keys to edit
the list of solvents.
A, B, C, and D are not valid
user-entered solvent names.
