The Rheos 2000 has over the last few years established itself as a hot tip for a growing community of analytical chemists. This has been mainly due to its reliability, low delay volume and extreme accuracy in delivering solvents at low flow rates. The total biocompatibility of all wetted surfaces in this system really sets it apart from its competitors. It has proven itself as the LC of choice for use with Mass Spectrometry (MS). Our customers like it especially for its outstanding performance in high-throughput applications, capillary- and nano-LC. The Rheos 2200 platform represents the next evolutionary leap of this exceptional concept. Amongst other things, the algorithm defining the cam shape has been further optimized, along with the micromechanics to further extend the performance at the lowest flow rates, down to 100 nL/min. The electronics have been refined and the four-channel degasser has now been integrated into the system.

Janeiro CNS software for advanced applications

Like the central nervous system in the human body Janeiro CNS is the centre for processing and dispatching of information in our system. In combination with Janeiro CNS, a sophisticated plug-in for Thermo's Xcalibur™ and ABI/Sciex' Analyst® software the user can now realise advanced chromatographic solutions using one system, rather than trying to synchronise a setup of separate software modules. This allows to effortlessly manage applications such as 2D-chromatography or column switching. With the HP Gradient Wizard Janeiro-CNS equally enables a special high-pressure gradient formation system (Rheos HPG system).
