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.
