Raman vs. IR Spectroscopy | Advantages & Limitations

Limitations: Since water strongly absorbs mid-IR radiation, measurement of aqueous solutions can be problematic, however using the ATR-IR technique mitigates this problem. The ATR-IR technique enablers solution phase to be analyzed, however particles in heterogeneous solutions are not measured. Because short pathlength flow cells are required due to strong IR absorption by most reaction mixtures, …

Infrared Technology for Hydrocarbon Gas Detection

LIMITATIONS OF ELECTROCATALYTIC TECHNOLOGY . The heart of an electrocatalytic or catalytic bead sensor is a platinum coil that is coated with a catalyst. This element is heated, and in the presence of a combustible gas a reaction takes place on the surface of this element with oxygen in the air to heat up the catalytic element. This causes a resistance change in the embedded coil that is measured and …
