FLOW SPLITTERS
For chemically destructive detectors such as in MS or ELS, a portion of the flow coming from the column must be split from the main flow stream to go to the detector for fraction triggering. Since the detectors must detect a peak before the fraction collector is triggered (delay time), the split flow must arrive at the detector before the main flow stream arrives at the fraction collector. To accomplish this, the split flow velocity is increased by using a “make-up pump” and “make-up solvent.”
Flow splitters can be either “passive” or “active”. Both passive and active flow splitters are equally effective at sampling the main sample flow hence the type of splitter employed is dependent upon user preference.
Passive splitters involve the use of restrictive tubing such as a delay coil and “T fittings” to maintain a specific flow rate range and split ratio.
An active flow splitter has two completely separated flow paths and a rapid switching valve that transfers a portion of the main flow stream into the make-up flow where it is diluted at a programmed split ratio.
