Authors: Felix Frank, Bettina Baumgartner, and Bernhard Lendl. Detecting traces of phosphates in water is critical for monitoring water quality in aquatic ecosystems. Mid-infrared techniques are effective for label-free and quick measurements in at-line or in-line applications, but sensitivity is limited due to high water absorption. To combat this, preconcentration schemes combined with evanescent field...Read More

Authors: Dominik Wacht, Mauro David, Hermann Detz, Bettina Baumgartner, and Bernhard Lendl. Mid-infrared attenuated total reflection (ATR) spectroscopy is a powerful tool for in situ monitoring of various processes. Mesoporous silica, an extensively studied material, has already been applied in sensing schemes due to its high surface area and tunable surface chemistry. However, its poor...Read More
