Extremely stable supramolecular sulfur polymer

Dual-mode, high-sensitivity, near-infrared, polymer optical sensor base on the thicker active layer

Highly sensitive mass spectrometry of non-polar organic compounds with supercritical fluids Coupling supercritical fluid extraction/chromatography (SFE/SFC) with proton transfer reaction (PTR) mass spectrometry (MS) to achieve quick sample preparation, high throughput analysis, and high sensitivity.
