Flow Splitter Makeup



           The ASI Makeup Flow Splitter is designed for 
           post-column applications. Both adjustable and 
           fixed-ratio splitters are available.




These splitters are suitable for many applications. The most common one is to split the outward flow of a preparative column and to accelerate the low-flow split with a Makeup pump. This Makeup flow is then directed to a detector that controls the fraction collection of the remaining preparative stream.

Adjustable Makeup-FlowSplitters are particularly recommended for use with different detectors that require different inlet flow rates.

Performance characteristics

Performance characteristics

  • Fixed and adjustable models available
  • Adjustable splitter for precise, direct control of the split ratios
  • Ideal for splitting low flows for analytical detectors in preparative HPLC
  • Extremely low dead volume (100 nl), so no influence of solvent viscosity on the split ratio
  • Flow rates 1 ml/min - 150 ml/min

  • All models with integrated Makeup port and delay coil
  • Fast, uncomplicated installation
  • Easy access for replacement of filters and flow resistor cartridges

Fixed Makeup Flow Splitter

Fixed Makeup Flow Splitter

The design of a fixed Makeup flow splitter is illustrated here. Each flow splitter is individually tested and calibrated for the stated input flow and the defined split ratio. With water and at the calibrated flow-rate, these splitters produce a back pressure of approx. 35 bar. The back pressure and the output flow change proportionally to the input flow, the split ratio, however, remains the same.
It is specified as +/- 15 %.





To ensure that the back pressure is not too high, please state your normally used input flow rate when placing your order.

Adjustable Makeup Flow Splitter

Adjustable Makeup Flow Splitter

Configurations available: Makeup flow splitter with adjustable input flow rate and fixed split ratio as well as splitters with fixed input flow rate and adjustable Makeup flow splitters, supplied with a calibration data sheet listing the required settings for the split ratio desired.
With water, and at the calibrated flow rate, these splitters produce a back pressure of 35 bar. The back pressure and the output flow rate change proportionally to the input flow rate, although the split ratio remains the same.
It is specified as +/- 15 %.

To ensure that the back pressure is not too high, please state your normally used input flow rate when placing your order.
