X-LCTM

Xtreme LC  Ultra High Pressure Chromatography Systems operating up to 15,000 PSI for use with sub 2um packed columns Applications in High-speed and high-resolution separations using small particle sizes typically 1.5 to 2um Proteomics LC-MS Fluorescence - JASCO is the only company with a fluorescence detector capable of handling the narrow peak widths produced by X-LC columns The New JASCO X-LC system is completely modular and can be used in any combination and with any mass spectrometer Check out the systems page

If you take a look at a Van Deemter curve for particle size versus resolution - you can see why column manufacturers have been working to develop packing materials with particle sizes smaller than 2um to provide ever increasing resolution for high speed and for separating complex mixtures.  The downside is that the small particle size and narrower columns cause extremely high back pressures resulting in the need for systems to deliver precise flow under difficult conditions. The New X-LC system from JASCO can operate from analytical pressures right up to 15,000 PSI.   Key Features Isocratic or High pressure gradient Binary solvent systems comprising one or two JASCO PU-2080ultra or PU-2085ultra pumps. Flow rate ranges are from around 10ul/min to 10ml/min including gradient mode. Pressures up to 15,000 PSI Detection can be either conventional UV using the new JASCO X-LC detector with high speed response or increasingly LC-MS for proteomics applications.
