How It Works - Agilent Technologies G3183B Installation And Operation Manual

How It Works

The splitter divides the effluent from a column among three different
detectors. The detectors can be operating at different pressures, that is, any
mix of the following can be used:
• Atmospheric pressure
• Below atmospheric pressure
• Above atmospheric pressure
The split ratio is determined by the length and diameter of tubing connecting
the splitter to the detectors. Tubing dimensions may be determined from
Table 2
included for calculating tubing dimensions for special situations.
Figure 1 shows the plumbing configuration for the G3183B splitter.
