Shimadzu's New System Enables Users To Upgrade From Standard UFLC To High-Pressure UFLC For Specialized Applications
Adding to its Prominence line of HPLC chromatography products, Shimadzu Scientific Instruments introduced the Prominence UFLCXR, an ultra fast liquid chromatograph (UFLC) with extra resolution, at Pittcon 2008 on March 1. Even at a high-pressure configuration, this flexible system delivers results without loss in basic chromatographic performance. Thanks to its Direct Injection with Isolated Metering System (DIIMS) (patent pending), only Shimadzu's Prominence UFLCXR can achieve high speed, high precision, low carryover and good linearity - all at the same time.
Optimized to enable high-speed analysis using the Shim-pack XR-ODS II series of columns (2 mm and 3 mm with 8 nm pores), the Prominence UFLCXR is capable of system pressures up to 9500 psi (66 MPa) for special situations that demand extra resolution (XR). Unlike many high-pressure systems, the system delivers data with high integrity and reproducibility, a result of fully re-engineered components in the injection valve.
"Fast chromatography at reasonable pressures is the most robust solution for generating highly reproducible data and the Prominence UFLC gives users just that," said Curtis R. Campbell, PhD, HPLC Product Manager. "When presented with a unique challenge that demands the use of longer columns for extra resolution, users can convert their current Prominence UFLC to an XR system or can purchase a new UFLCXR system. Together, they represent the ultimate solution."
The Prominence UFLCXR system is up to 10 times faster than a conventional HPLC system that uses a 5-µm particle column. New SIL-20AXR and SIL-20ACXR autosamplers are capable of 10-second injection cycles while delivering <0.3 % RSD area repeatability. Prominence UFLCXR also successfully reduces carryover by inhibiting the adsorption of samples through precise engineering and the prudent choice of wetted materials in the flow path.
With its micro-plunger design, the LC-20ADXR solvent-delivery system provides unmatched gradient resolution and reproducibility, and has a delivery range of 100 nL/min to 10 mL/min. Prominence UFLCXR accepts an assortment of flow-control valves and a column-switching system, allowing for use with many other applications, such as two-dimensional HPLC or micro to semi-micro analysis.
