Assured Reliability and Reproducibility

Consistent Analysis Reproducibility Improves Quantitative Analysis Performance

In order to reduce the effect of adsoprtion of metal-sensitive compounds, a system is often passivated by repeatedly Adsorption of target compounds can be especially detrimental in the low-concentration region, and can worsen
injecting samples that contain the target compounds before starting data acquisition. However, this approach not calibration curve linearity. The Nexera XS inert achieves a wider dynamic range by strongly increasing the quantitative
only wastes valuable samples and time, but can make it extremely difficult to acquire reliable data due to changes in accuracy and detection of low-concentration samples.
the state of passivation during continuous analysis. Nexera XS inert systems eliminate the need for the preliminary
passivation and provide highly reliable data from the first injection and throughout the analytical session.
