Bright future for trace water analysis

MOF-based material has detection limit as low as traditional Karl Fischer titration

Researchers from Germany have devised a new way to detect trace water in solvents. Their technique combines luminescent metal–organic frameworks (MOFs) with a magnetic core to give a system that users can see change colour then fish out of the sample once the test is complete.
