The Agilent diamond ATR/Transmission sampling accessory for the Agilent Cary 630 FTIR is a single bounce ATR specifi cally designed to optimize the energy throughput, ensuring you achieve the highest quality spectra. Traditional diamond ATRs signifi cantly reduce throughput, reducing the sensitivity compared to direct transmission measurements. The unique design of the Cary 630 FTIR and the diamond ATR increases energy throughput around 30% compared to other routine FTIR systems, enabling faster data collection, lower noise and superior quality.

The diamond ATR for the Cary 630 FTIR takes advantage of the physical properties of light when encountering two materials with differences in index of refraction. When coming in contact with a sample having a different index of refraction, the infrared light creates an evanescent wave, which provides a very small and specifi c depth of penetration into the sample with each internal refl ection. This small and consistent pathlength means good quality spectra can be acquired from a wide variety of samples with no sample preparation. The key to obtaining these results with the diamond ATR accessory is to make good contact between the sample and ATR crystal.

The Agilent Cary 630 FTIR spectrometer is a flexible benchtop FTIR instrument offering high performance and extraordinary ease-of-use in an ultra-compact design. It is engineered with the user in focus and provides simple, intuitive workflows to deliver meaningful answers in routine FTIR spectrometer analysis and cutting-edge research.

The Cary 630 FTIR spectrometer is a robust, reliable, and flexible benchtop FTIR instrument benefiting from Agilent’s experience with field-proven mobile and handheld FTIR spectrometers. Its modularity offers sampling flexibility for analysis of solids, liquids, powders, and gases. Permanently aligned optics allow a wide range of modules to be swapped in and out in seconds, providing superior quantitative and qualitative information – fast.
