The Agilent Cary 630 Diamon ATR FTIR is a compact benchtop Fourier Transform Infrared spectrometer.

• Interferometer geometry: High-throughput Michelson interferometer with fixed and moving flat mirrors
• Spectral range: 7000 to 350 cm⁻¹
• Detector: 1.3 mm diameter, thermoelectrically-cooled dTGS
• Software: Agilent MicroLab suite
• Sampling Accessory: The Diamond ATR (Attenuated Total Reflectance) sampling accessory uses a type IIa diamond crystal as the interface between the sample and infrared beam, providing exceptional durability and chemical resistance across a wide pH range (1–14). This makes it ideal for analyzing hard, abrasive, or corrosive materials. As a single-reflection ATR, it is optimized for strongly absorbing samples such as rubbers, polymers, paints, fibers, powders, and solids. A sample press ensures good contact with the 1 mm diamond surface, which offers a 200 µm active area and ~2 µm penetration depth at 1700 cm⁻¹. The Diamond ATR is especially useful when only small amounts of sample are available.
