Zeolitic imidazolate framework nanocrystals for enrichment and direct detection of environmental pollutants by negative ion surface-assisted laser desorption/ionization time-of-flight mass spectrometry†
Abstract
Zeolite imidazole framework (ZIF) nanocrystals serve as sorbents and matrices for negative ion surface assisted laser desorption/ionization mass spectrometry. The unique properties of ZIFs make them suitable for analyzing a series of environmental pollutants with high signal intensity and a clean background.
