Details:

Amorphous material transmitting IR (AMTIR) has very low water solubility and good chemical resistance – particularly to acids. It generally performs well in a pH range of 1-9. Although AMTIR contains arsenic and selenium, it is generally considered safe to handle. Coated versions of our AMTIR ATR crystals are available for improved IR throughput and enhanced seal within the ATR crystal plate.
