Unconstrained Recovery and Sensitivity

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.

The Nexera XS inert system is equipped with unique technology that ensures the complete inertness of the sample
The Nexera XS inert can detect oligonucleic acids with a strong tendency of metal adsorption. flow path. The system provides excellent peak shape and unsurpassed chromatographic separation by effectively
inhibiting the adsorption of target compounds to internal surfaces.
