Flow Splitters for Chromatography

Model 62 Stainless Steel Adjustable Flow Splitter
For Pre and Post Column Applications
Splitters
• Bracket Mounted
• Adjustable Metering
• Precise Direct Control
• Fluid Resistor Technology
• Split ratios from 1:1 to 20,000:1
• Low Dead Volume
• Rugged Steel Design
• 5,000 PSI Valve Limit
Adjustable Flow Splitters make it easy to create split ratios from 1:1 up to as high as 20,000:1. Because the Adjustable Flow Splitter incorporates a metering valve, split ratios can be changed frequently with flow changes that are stable and reproducible as noted in figure 1.0. Our Model 62 splitter valve ratios are not affected by changes in solvent viscosities or pressure, which makes this product acceptable for gradient and isocratic applications. Other applications include SCF/MS, where large viscosity changes may be encountered during gradient runs. Applications include isocratic and gradient methods where a reproducible change in the split ratio is acceptable.

Split ratios are created by 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 resulting ratios are stable and repeatable. Because of 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.

Pre-Column splitting is used for micro, capillary and nano HPLC applications. Keep in mind that even though the split ratio created by the splitter valve will remain constant; when an HPLC column is installed there will be added resistance on the flow rate channel from the HPLC column. This added resistance must be factored in to make sure the fluid resistor selected for the flow splitter provides the correct split ratio. When ordering a pre-column flow splitter please provide Analytical Sales with the column flow rate and back pressure. If the inlet flow rate or column pressure specifications are not provided, Analytical Sales will configure pre-column flow splitters assuming a 0.5mL/min inlet flow rate and a pressure drop across the column of 1500 PSI.

Adjustable Pre-Column Flow Splitters
Pre-Column splitting is used for micro, capillary and nano HPLC applications. The split ratio created by the splitter valve will remain constant, however, when an HPLC column is installed there will be added resistance on the flow rate channel. This added resistance must be considered to ensure the fluid resistor selected for the flow splitter provides the correct split ratio.

When ordering a pre-column flow splitter, please provide the column flow rate and back pressure specifications. If these specifications are not provided, the pre-column flow splitter will be configured assuming a 0.5mL/min inlet flow rate and a pressure drop across the column of 1500psi.

Model 63 and 53 Fixed Binary and Multiport Flow Splitters

• Fixed metering for precise control
• Fluid Resistor Technology
• Split ratios from 1:1 to 2,000:1
• Low dead volume
• Rugged stainless steel design

 

 

 

The Advantage Fixed Flow Splitters are shipped with resistors installed that deliver the nominal stated split ratio. The split ratios have a tolerance range of ±10%. The exact split ratio is measured and is stated on the certificate shipped with the splitter. The input flow rate can be adjusted to compensate for the tolerance in split ratios. For instance, a 10% increase in input flow rate will result in a 10% increase in flow at both the capillary and waste stream channels. Flow rate and viscosity changes will change the backpressure generated by the splitter, but will not affect the actual split ratio.

These fixed  Flow Splitters can be used for LC/MS, Flow Fractionation, Column Flow Splitting and Capillary Chromatography.
