ASI QuickSplit Flow Splitters
T
he ASI QuickSplit Flow Splitter is very elegant in its simplicity. Split ratios are created by two or more fluid resistors that form a
parallel flow path. QuickSplit Flow Splitters are available with a fixed or adjustable split ratio. Interchangeable fluid resistors make
it easy to change split ratios quickly, eliminating tedious adjustments to capillary tubing. The technology can be applied to all
applications where a controlled, reproducible split ratio is required including LC/MS, flow fractionation, pre/post-column flow splitting mass
directed fraction collection, and capillary chromatography. ASI QuickSplit Flow Splitters come in flow rate ranges which make them com-
patible with micro, analytical, semi-preparative and preparative inlet flows.
QuickSplit Flow Splitter Features:
•
Fluid resistor technology eliminates tedious adjustments to capillary tubing for split ratio optimization
•
Split ratios are stable and reproducible, and not affected by changes in viscosity or pressure
•
Adjustable splitters enable precise direct control over split ratios
•
Easy to use interchangeable fluid resistors make it possible to achieve split ratios from 1:1 to 20,000:1
•
Applications include LC/MS, pre/post-column flow splitting, and flow fractionation
•
Multiport flow splitter diverts the inlet flow into 3 or 4 channels for applications that employ multiple detectors and/or a
fraction collector
•
Rugged stainless steel construction allows high pressure operation
•
Low dead volume fluidic design
•
Unique flow path geometry resists clogging better than capillary tube resistors
QuickSplit Fixed Flow Splitters
Unlike conventional splitters that use long lengths of capillary tubing, the ASI QuickSplit Fixed Flow Splitter uses two compact fluid
resistor elements which are designed as cartridges for easy replacement. The flow path of the QuickSplit Fixed Flow Splitter contains two
fluid resistors that form a parallel flow path. Both low and high flow rate streams pass through fixed resistor cartridges. The ratio of these
two resistors creates the split ratio.
Schematic flow diagram of the QuickSplit™ Fixed Flow Splitter
L1 = Fixed fluid resistor (resistance value varies depending on cartridge rating)
L2 = Fixed fluid resistor (resistance value varies depending on cartridge rating)
R = Split ration = Q1/Q2 = Resistance ration = L2/L1
Since the flow rate is indirectly proportional to resistance, changing the resistance in either flow path results in a change to the split
ratio. Changing resistance is accomplished by exchanging the fixed fluid resistor cartridges with a resistor set that has different resistor
ratings.

Fixed Flow Splitters - Post-Column Applications
Post-column splitting is fairly straight forward. Devices contribute to chromatographic dispersion so care must be given to connecting
tubing and fittings, especially at low flow rates. The pressure drop specification for all input flow ranges is 500psi with water at the corre-
sponding inlet flow rate respectively. To assure a maximum pressure drop of 500 psi across the splitter, please specify the inlet flow when
the splitter is ordered.
QuickSplit Binary Fixed Flow Splitter
This easy to use “plug and play” device comes with a
predefined split ratio eliminating tedious adjustments to
capillary tubing. Split ratio changes are accomplished by
changing the resistor set. The split ratio is determined by
the ratio of fluid resistors installed in the splitter manifold.
The pressure drop across a fixed splitter for post column
applications is typically low, less than 500 psi. The low
internal dead volume prevents excessive dispersion and
the replaceable inlet filter insures robust operation.
Available in models for analytical, semi-preparative,
preparative, and high preparative inlet flow rates.

Fixed Flow Splitters - Pre-Column Applications
P
re-column splitting is used for micro, capillary, and nano HPLC applications, where the flow from the pump is split from analyti-
cal flow rates down to microliter or nanoliter flows. It is important to note that even though the split ratio created by the splitter
valve will remain constant, the split ratio will change when a HPLC column is installed. This is due to the added resistance on
the low flow rate channel from the HPLC column. This added resistance must be factored in to make sure the fluid resistors selected for
the flow splitter provide the correct split ratio.
When ordering a pre-column flow spitter please provide SIS with the column flow rate and back pressure. If the inlet flow rate or col-
umn pressure specification is not provided, SIS will configure pre-column flow splitters assuming a 0.5 mL/min. splitter inlet flow rate and
a pressure drop across the column of 1500 psi. Adjustments to the low flow rate channel can be made by increasing or decreasing the
splitter inlet flow rate.
QuickSplit™ Binary Fixed Flow Splitter
This easy to use “plug and play” device comes with a prede-
fined split ratio eliminating tedious adjustments to capillary tubing.
Split ratio changes are accomplished by changing the resistor set.
The split ratio is determined by the ratio of fluid resistors installed
in the splitter manifold. The pressure drop across a fixed splitter for
pre-column applications where the pressure is nominally 1,500 psi.
The low internal dead volume prevents excessive dispersion and
the replaceable inlet filter insures robust operation. Available in
models for analytical inlet flow rates.
Analytical Splitters - Binary
Analytical range, 0.1 mL/min. to 0.5 mL/min. input flow
The pressure drop across a pre-column flow splitter will generally be between 1,000 psi and 3,500 psi. The exact pressure drop will
depend on how the splitter is configured.

QuickSplit Makeup-Flow Splitter Manifolds
T
he ASI QuickSplit Makeup-Flow Splitter Manifold is designed for post-column applications where a small amount of flow from
an HPLC column is efficiently combined with a makeup-flow before it reaches the detector. Although there are many variations
of this type of application, one of the most common involves splitting a small portion of the outlet flow from a preparative HPLC
column which is then combined and diluted with a makeup-flow. The combined makeup-flow is used by a detector, typically Mass Spec.
or UV, to trigger fraction collection from the remaining flow. A minimum delay time of 5 seconds (maximum inlet flow) is built into the split-
ter to insure proper sequencing between detection and fraction collection. Unique integral design eliminates tees and fittings within the
splitter, resulting in extremely low peak dispersion. An additional splitter can be added after the manifold to allow splitting the makeup-flow
stream prior to entering the detector.
Custom configuration orders must include inlet flow, split ratio, and delay time. In order to assure <500 PSI pressure drop across the
splitter, please specify the inlet flow when you order.

QuickSplit Adjustable Flow Splitters
U
nlike conventional splitters that use long lengths of capillary tubing,
the ASI QuickSplit Adjustable Flow Splitter uses fluid resistors to
achieve a wide range of split ratios. The flow path of the QuickSplit
Adjustable Flow Splitter contains two fluid resistors that form a parallel flow path.
The low flow rate stream passes through a fixed resistor cartridge, while the high
flow rate stream passes through an adjustable fluid resistor (metering valve).
The ratio of these two resistors creates the split flow ratio. The compact fluid
resistor elements are designed as cartridges for easy replacement with resis-
tance values (L2) rated in PSI/mL/min. Because of the extremely low internal
volume of the fluid resistors, the solvent composition in both resistors at any
instant in time is the same, and therefore viscosity changes associated with gra-
dient runs do not impact the split ratio.
Due to the rugged design, the split ratio repeatability is +/- 1 % of setting, and
unlike alternative splitter valves or tees, will not be affected by actions that effect
input flow such as turning the pump off and on, or pressure spikes. Because the
QuickSplit Adjustable Flow Splitter incorporates a metering valve, split ratios can
be changed frequently with flow changes that are stable and reproducible. The
QuickSplit Adjustable Flow Splitter will create split ratios that are not affected by
changes in solvent viscosity or pressure and provides direct real time control
over split ratio optimization.
Schematic flow diagram of the QuickSplit™ Adjustable Flow Splitter
L1 = Adjustable fluid resistor (metering valve)
L2 = Fixed fluid resistor (resistance value varies depending on cartridge rating)
R = Split ration = Q1/Q2 = Resistance ration = L2/L1
Since the flow rate is indirectly proportional to resistance,
changing the resistance in either flow path results in a change
to the split ratio. Changing resistance is accomplished by
adjusting the metering valve on the high flow rate channel or
exchanging the fixed fluid resistor cartridge in the low flow rate
channel with a resistor cartridge which has a different resis-
tance rating. Adjusting the metering valve is analogous to
changing the capillary tubing length or diameter on conven-
tional tee type flow splitters. The QuickSplit Adjustable Flow
Splitter has a convenient mounting bracket and hand adjust-
ment knob to control the split ratio. The split ratio is adjusted
by turning the adjustment knob. Split ratios are increased by
turning the adjustment knob clockwise, and decreased by
turning the knob counter-clockwise. Split ratios are not affect-
ed by changes in solvent viscosities or pressure, which makes
this product suitable for gradient applications as well as iso-
cratic. The QuickSplit Adjustable Flow Splitter is shipped con-
figured for either post-column or pre-column applications.

Adjustable Flow Splitters - Post-Column Applications
P
ost-column splitting is fairly straight forward. Like pre-column flow splitting, any significant additional pressure (resistance) down-
stream from the splitter may affect the split ratio. Post-column devices also contribute to chromatographic dispersion so care
must be given to connecting tubing and fittings especially at low flow rates.

Adjustable Flow Splitters - Pre-Column Applications
P
re-column splitting is used for micro, capillary, and nano HPLC applications, where the flow from the pump is split from analyti-
cal flow rates down to microliter or nanoliter flows. It is important to note that even though the split ratio created by the splitter
valve will remain constant, the split ratio will change when a HPLC column is installed. This is due to the added resistance on
the low flow rate channel from the HPLC column. This added resistance must be factored in to make sure the fluid resistors selected for
the flow splitter provide the correct split ratio.
When ordering a pre-column flow splitter please provide SIS with the column flow rate and back pressure. If the inlet flow rate or col-
umn pressure specification is not provided, SIS will configure pre-column flow splitters assuming a 0.5 mL/min. splitter inlet flow rate and
a pressure drop across the column of 1500 psi.
Analytical Splitters
Analytical range, 0.25 mL/min. to 1 mL/min. input flow
These splitters will produce under 3,500 psi backpressure with water at 0.5 mL/min..
