Flow Splitter for Fractionation Triggered by LC/MS Signals


               For fractionation triggered by LC/MS signals, a portion of the sample must be introduced into the LC-MS.
                 The dedicated flow splitter splits a small portion of the flow from the preparative stream to the MS stream. This enables the use
               of LC-MS detection signals for triggering fractionation while maintaining a high recovery rate.

                                                      By splitting the stream into two after separation by the column, a large
                                                      portion is introduced to the fraction collector side and a small portion
                                                      to the MS side.
