ATR is a universal sampling accessory for analysing solids, polymer, rubber, powders, liquids, pastes and gels. With high IR throughput, it is ideal for sample identification and QA/QC applications. Easily changeable crystal plate design provides analysis of a broad spectrum of sample types while ensuring constant sampling path length. In the optical design, the ATR crystal both focuses the IR beam and provides the ATR sampling interface. This technology provides much higher throughput than competitive products and saves you considerable time and provides you higher quality spectra.
