Nexsa G2 XPS is equipped with a new X-ray monochromator, which can realize continuous adjustment of X-Ray spotsize ranging from 10 um to 400 um, with step size at 5 um. This ensures that the analysis beam spot can be adjusted to match the target features, maximizing signal enhancement. By utilizing upgraded X-ray sources, efficient electronic lenses, and optimized detectors, excellent sensitivity and fast data collection can be achieved. The one click automatic charge compensation system on this system can easily realize insulation sample analysis; The equipped standard ion source or MAGCIS (optional single particle and gas cluster composite ion sources) can be used for depth profiling research. Automatic ion source optimization and gas path control system ensure excellent performance and experimental reproducibility.
