The QUALISURF® QSF-22: A Benchtop NIR Chemical Analyzer

The precision, speed and a wide range of NIR spectroscopy make it highly useful in the development of chemical metrology, specifically for cleaning and etch processes.

The QUALISURF® QSF-22 integrates NIR spectroscopy with ECI Technology’s Smart-BT software to support the advancement of quantitative analyses of new chemicals for quality control and process optimization.

The speed, ease, cost-effectiveness and precision of the QSF-22 analyzer are the perfect fit for developing new chemistries, particularly when analyzing proprietary chemistries. The QSF-22 analyzer can also be used by chemical suppliers for quality control.

Apart from typical NIR spectroscopy that can simply acquire spectra, the QSF-22 analyzer can examine the spectra, produce recipes and easily transfer them to ECI’s QUALISURF Online Analyzers to quantify the target chemicals.
