Thermo Fisher Scientific has announced the expansion of its quaternary solvent delivery systems with the release of the Accela 600 HPLC and Accela 1000 U-HPLC.
The Thermo Scientific Accela 600 and Accela 1000 are designed to enable rapid method development while reducing solvent consumption.
Both Accela systems feature force feedback control (FFC), which enables the delivery of accurate and precise gradients under all operating conditions.
'The capabilities of the new Accela 600 and Accela 1000 systems increase laboratory productivity,' said Andrew Altman, vice-president and general manager of liquid chromatography, Thermo Fisher Scientific.
'The systems provide increased flexibility for conventional and ultra-high performance applications.
'The Accela systems, equipped with FFC technology, deliver excellent compositional and flow rate accuracy and precision resulting in high levels of reproducibility.
'When coupled with the Thermo Scientific LTQ Velos, these new products create a fast LC-MS with increased ion trapping efficiency and lower fragmentation times.
'The faster scan rates of the LTQ Velos allow more MSn experiments to be carried out in shorter chromatographic runs,' he added.
Developed specifically for use with Thermo Scientific Hypersil columns packed with five, three and the 2.4 micron particle diameter, the Accela 600 provides flow rates up to 5ml/min and a maximum operating pressure of 600 bar with only 90ul of delay volume.
The Accela 1000 has a maximum operating pressure of 1,000 bar with only 65ul of delay volume, making it suitable for U-HPLC applications using columns packed with sub 2.0 micron particles such as the Hypersil Gold.
The Accela 1000 is claimed to be the only U-HPLC instrument on the market with a quaternary solvent delivery system and optimised gradient accuracy.
This combination of features gives the user the flexibility to use the Accela 1000 as a stand-alone LC or as a front-end system for applications that integrate mass spectrometry.
The Thermo Scientific Open Accela Autosampler delivers increased throughput, durability and minimal carryover in an open access platform.
The vertically designed Open Accela Autosampler provides a compact solution that is configurable for all applications.
The Thermo Scientific Accela PDA is said to improve sample identification with increased sensitivity and an acquisition rate up to 80Hz.
The PDA's Lightpipe technology enables fast separations by employing a 1cm path length in a 2ul flow cell.
The low level of dispersion in the Lightpipe technology allows the flow cell to retain excellent peak shape and chromatographic resolution.
The Accela U-HPLC system optimises the performance of sub-2um particle columns, providing seamless operation spanning conventional LC pressures from short LC columns up to 15,000 psi for long-column separations of complex samples, according to Thermo Fisher.
