Shimadzu Scientific Instruments introduces the Nexera ultra high-performance liquid chromatography (UHPLC) system, which delivers high-speed and high-resolution analysis without sacrificing basic performance parameters such as excellent precision, near-zero carryover, good linearity, stability and ruggedness.
Offering these attributes enables Nexera to provide superior performance in various fields, covering high-resolution and high-speed separation, as well as high-sensitivity detection.
Shimadzu’s Nexera is optimized to enable analysis at pressures up to 130 MPa. Without compromising performance and data quality, the maximized pressure over a wide flow range enables various types of analyses, including micro LC to conventional LC, regular pressure LC to ultra high-pressure LC, and isocratic LC to ternary high-pressure gradient and multi-dimensional LC. The system is also suitable for LC-MS applications.
Nexera’s fast injection — just 10 seconds — enables fast chromatography to shorten cycle time and result in true high throughput with 4,600-plus sample capacity. Nexera’s newly designed injection port and fine-tipped needle, along with additional features such as multiple-rinse solvent selection and injection port and internal needle rinse, reduce carryover to an absolute minimum.
The autosampler also offers fixed-loop injection for ultra-fast separation with minimized peak width and gradient delay. An overlapping injection function is standard with Nexera to allow for a maximum reduction in cycle time.
For high-temperature LC analysis, Nexera offers efficient pre-heating for solvents to enable stable and reliable conditions. The advanced Intelligent Heat Balancer (IHB) minimizes band broadening during high-temperature analysis through the use of independently controlled heat zones within the column compartment. This ensures accurate column temperature regardless of flow rate. The post-column cooler can reduce detector noise when equipped for high-temperature analysis up to 150 degrees C.
