Supercritical fluid chromatograph is a completely automated system that uses supercritical fluid carbon dioxide as a mobile phase for analytical separations
High temperature liquid chromatography (HTLC) specialist Selerity Technologies launches its latest instrumentation - the series 4000 supercritical fluid chromatograph (SFC).
The SFC is a completely automated system that uses supercritical fluid carbon dioxide as a mobile phase for analytical separations.
Selerity has addressed the limitations of gas and liquid chromatography to separate compounds prone to thermal instability, and subject to other causes of ineffective separations, including a lack of chromophores.
The company initially developed the series 3100 SFC to overcome these shortcomings, and the new 4000 series SFC takes productivity and efficiency to new levels.
Marketed at both the niche capillary SFC and petroleum markets, the series 4000 harnesses the latest developments in supercritical fluid chromatographic methods.
The series 4000 consists of a high capacity force air oven with a flame ionisation detector for rapid heating and cooling; a 10ml syringe pump for pulse-free mobile phase delivery and minimal usage of carbon dioxide; an autosampler, and an integrated data acquisition software package. This groundbreaking instrument is uniquely designed to accommodate capillary columns and 1mm packed columns manufactured for SFC use.
The series 4000 also eliminates pressure fluctuation created from the surrounding environment by the use of a revolutionary temperature controlled pressure transducer, a syringe pump for continuous mobile phase delivery, and split/splitless injection for high volume capillary column injections.
The series 4000 is fully compliant with the two standard American Society for Testing and Materials (ASTM) methods in the use of supercritical fluid chromatography - ASTM D5186 and ASTM D6550.
These standards are widely accepted within the petroleum industry.
