Selerity Series 4000 SFC - 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
