Screen 8. Splitter Valve Period Selection.
The Econo Gradient Pump automatically detects the presence of a
splitter valve. The default period is 2 seconds. This parameter, in
conjunction with the “%-split” parameter, may be varied for stream
splitting, process sampling, or on-line biological activity assays. More
information is included in the splitter valve instruction manual. If you
are uncertain about this value, accept the default of 2 seconds and
adjust it later according to your application needs.
