Multiloop-MIR Fiber Optic ATR Probes

This MultiLoop-MIR™ system is perfect for analyzing liquids, pastes, and soft solids outside of the FTIR spectrometer sample compartment. These multiple reflection ATR probes are used in conjunction with the Harrick FiberMate2™ or other fiber optic coupler.  The MultiLoop-MIR™ includes one CIR and one PIR fiber optic probe, each with a set of five disposable loop tips. This combination is designed for spectral measurements across the entire mid-infrared region. To analyze a sample, simply dip the ATR loop tip into the sample or press it gently against the sample.
