Equipped with a single-reflection ZnSe crystal for reliable and efficient ATR measurements High infrared throughput for enhanced signal quality Suitable for direct analysis of solids, polymers, rubber, powders, liquids, pastes, and gels Optional crystal materials available, including ZnSe, Ge, diamond, and Si, to suit different application requirements High-pressure clamping mechanism with a maximum load of up to 18 kg (40 lbs) Crystal diameter of 1.8 mm, capable of achieving contact pressures up to 10,141 psi Interchangeable pressure tips (swivel, flat, and concave) for various sample types Dedicated liquid sampling accessories available   ATR is a universal sampling accessory designed for the analysis of solids, polymers, rubber, powders, liquids, pastes, and gels. With high infrared (IR) throughput, it is ideally suited for material identification as well as quality assurance and quality control (QA/QC) applications. The interchangeable crystal plate design enables flexible analysis across a wide range of sample types while maintaining a constant and reproducible sampling path length. In the optical configuration, the ATR crystal functions both as the IR beam focusing element and as the sampling interface, ensuring efficient energy coupling. This advanced optical design delivers higher throughput compared to conventional ATR systems, significantly reducing analysis time while providing superior spectral quality and improved analytical reliability.
