SEIRAS optimized ATR Crystals

Suitable for Surface Enhanced Infrared Absorption Spectroscopy

We optimized our basic Single Reflection ATR Crystals for Surface Enhanced Infrared Absorption Spectroscopy (SEIRAS) by increasing the angle of incidence from 20° to 49°. A gold layer can be applied to the surface for functionalization.

These crystals have recently been tested by researchers in Canada. You can read more about this in their publication on Electrochemical ATR-SEIRAS.

Please note that these crystals come without the gold layer.
