Ultra high-performance liquid chromatograph Nexera XS inert

laboratory

The potential adsorption of an analyte onto wetted surfaces of UHPLC instruments poses some critical challenges when analyzing biomolecules. While elevated pressure tolerance is required to achieve optimal chromatographic separation when using small particle size columns the inertness of the wetted surfaces is also of the utmost importance, as is resistance to corrosion due to the use of mobile phases with high salt concentrations and extreme pH values. The Nexera XS inert system offers the ideal solution for the separation of biomolecules by combining the elevated pressure tolerance of a UHPLC system with complete inertness of the sample flow path, ensured by the absence of wetted metal surfaces and offering ultra-high resistance to corrosion. Unconstrained Recovery and Sensitivity Reduces sample loss due to adsorption to metal and achieves excellent sensitivity. Clear Resolution without Restrictions Improves peak shape and achieves excellent chromatographic separation. Assured Reliability and Reproducibility Reliable data for metal-adsorbing compounds with high reproducibility For the quantitative analysis of biomolecules, particularly when high sensitivity is required, the adsorption of the target compound to a metal surface can result in a dramatic decrease in sensitivity. The Nexera XS inert system prevents peak tailing and sensitivity loss by eliminating adsorption of proteins, nucleic acids, and other components to metal surfaces. As a result, reliable and accurate quantitation is possible, even for low-concentration samples.
