The Spectropus™ Remote Sampling System Spectropus™ is a versatile optical sampling system capable of performing spectroscopic analyses on remotely located and/or large samples. Specially designed Sampling Terminals, employing different spectroscopic techniques, are provided as integrated components of the system. The Sampling Terminals may be located some distance from the spectrometer and are connected to it via a purged optical Transfer System which is designed for maximum optical efficiency. Each terminal may be located in the laboratory, in a glove box, and/or at strategic places along a process line. More than one Sampling Terminal can be connected to the spectrometer. Applications Custom-designed for infrared analyses of local and remotely located samples, multiple sampling, samples in glove boxes, and large samples. Features Analyzes samples up to 15m away from the spectrometer. Highly efficient optical transfer system. Purgeable. Compatible with spectrometers with an external detector input and an external collimated beam port. Basic system includes Minimum Transfer System, Sampling Terminal Power Supply, and Sampling Terminal. Minimum Transfer System. Provides all equipment necessary to use the Sampling Terminals as an "external bench." Sampling Terminals feature: Dedicated detector and preamplifier. Separately purged for maximum sample throughput. Upward or downward looking mounting capabilities. Requires Harrick’s external Power Supply, available separately. Models currently available: Barrel Ellipse Diffuse Reflectance/Emission Sampling Terminal for examining films or contaminants. External Reflection Sampling Terminal for analyses at a 75° incident angle. Suitable for analyses of thin films on reflective substrates. TurboATR™ Sampling Terminal for single reflection internal reflectance studies at a 45° incident angle and temperatures ranging from ambient to 175°C. Gas Cell Accessory for use with other Sampling Terminal detectors. 6X Beam Condenser These 6X Beam Condensers are especially suitable for examining very small quantities of samples with use of 90° off-axis ellipsoids. They also provide sufficient working space for such accessories as high-pressure diamond cells. Applications Transmission and internal reflection studies of small quantities of liquids, pastes, and soft or flexible solids. Ideal for use with high-pressure diamond cells. Features Easily converts from internal reflectance to transmission to accommodate a variety of experiments. A spot 16% of the normal sample beam size, for more efficient irradiation of small samples. Fixed angle transmission beam condenser, providing a working space of approximately 40mm. Features large ellipsoids. Recommended for use with high-pressure diamond cells. Includes One pellet holder Mating hardware for the specified spectrometer. Emission Accessory Harrick’s Emission Accessory is a powerful tool for examining vibrational spectra of surface species. It can be attached to any spectrometer with an emission port. Includes XYZ translation stage. Interchangeable masks. Heater and K-type thermocouple. Mating hardware for the specified spectrometer. Applications Powerful tool for studying vibrational spectra of surface species. Features Translation stage for easy sample positioning. Interchangeable masks define the area of the sample surface analyzed. Collects the emittance over a large angular distribution. Permits sampling of small areas. Use with either a room temperature or cooled detector. Purgeable. Optional viewing microscope available for identification of areas of interest. Compatible with any spectrometer with an emission port. FastIR™ Reactor Applications Useful for real-time monitoring of liquid reactants and/or products via single reflection ATR.
