Thermo Scientific 222-289600 Smart ITR Internal Reflection Accessory with Germanium Plate for FT-IR Spectrometers

The Thermo Scientific 222-289600 Smart ITR is an internal reflection accessory for compatible Thermo Nicolet FT-IR spectrometers. It uses an integrated germanium (Ge) sample plate for direct measurement of solids, powders, viscous liquids, and pastes through internal reflection in the mid-infrared range.

The Smart ITR is designed for compact, low-volume FT-IR analysis. A sample volume of only 2–4 µL is sufficient, making it suitable for routine identification and qualitative analysis of polymer films, active pharmaceutical ingredients (APIs), cosmetic powders, food waxes, and related materials.
