Thermo Fisher Scientific has launched a quaternary pump that improves the separation of complex mixtures, such as red wine, during ultra-high-pressure liquid-chromatography (U-HPLC) analysis.
The Thermo Scientific Accela 1250 pump features force feedback control (FFC), which eliminates the need for pulse dampening while improving flow accuracy and gradient precision under extreme operating conditions.
The company is showcasing the Accela 1250 in Booth 2,757 at Pittcon 2010, which runs until 5 March in Orlando, Florida.
The pump is designed to operate at a top pressure of 1,250bar, with flow rates of up to 2ml/min.
This makes it suitable for U-HPLC analysis and applications requiring flexibility between standard HPLC and U-HPLC capabilities.
The improved pump also offers increased performance with significant baseline stabilisation and improved retention-time reproducibility, according to Thermo Fisher.
The Accela 1250 pump is an enhanced version of the Accela LC, which provides fast, efficient chromatographic separations over an expansive range of flow rates and pressures.
