Selerity Series 4000 Supercritical Fluid Chromatograph by Selerity Technologies, Inc.

The Selerity Series 4000 SFC was designed specifically for separations performed on microbore packed or capillary columns, in which a precision and pulse-free delivery of the mobile phase is critical. All systems are equipped with a flame ionization detector, optional specialty detectors, a low volume rotary injection valve, and a 10 mL high-pressure syringe pump. The Selerity Model 4000 SFC utilizes a Microsoft Windows 10 PC-based Agilent OpenLAB EZChrom chromatography data system software for signal acquisition and full instrument control.

Unique Features of the Selerity Series 4000

• High pressure syringe pump
• Delivers the supercritical carbon dioxide by controlling the set pressure; therefore, a pulse-free pressure is delivered throughout the column to the detector, with no dampening needed.
• Only a small amount of the carbon dioxide mobile phase is used for each analysis, and system is helium-free, reducing the total cost per analysis.
• Long lifetime for syringe pump seals and check valves, in comparison to reciprocating pump technologies.

Column technology

• 1mm ID Packed columns are optimized for SFC methods
• 50 μm capillary columns with a variety of phases are utilized
• Each column is tested under SFC conditions

Injection techniques

• Timed Split direct injections to minimize dead volume
• Split/Splitless injection available for enhanced peak shape

Temperature controlled pressure transducer

• Up to 10X improvement in retention time reproducibility
• Improvement in operating pressure accuracy
