The University of Southern Mississippi (USM) is looking to procure a React IR system capable of monitoring a reaction in situ and in real-time. Bidder shall meet or exceed the following specifications: General Diamond and silicon must both be available as ATR sensor materials All probe wetted parts should be compatible with typical organic reagents and solvents using no o-ring or brazed seals of any kind, and materials of probe construction must be chemically and physically inert consisting only of Hastelloy C-22 and gold The ATR sensor must have greater than 6 reflections or more for the best sensitivity An RTD (resistance temperature detector) must be integrated into the probe tip to automatically capture temperature of the reaction mass with each spectra collected The ATR sensor should not protrude outside the probe body eliminating the possibility of damaging the sensor A wide variety of sampling technology must be currently available for purchase fulfilling the requirements to monitor a wide variety of chemistry o Pressure range (vacuum to 310bar), Temperature range (-80 to 300C) o pH range from 1 to 14 (diamond sensor) o pH range from 1 to 9 (silicon sensor) The infrared energy should be transmitted to the sensor and returned to the interferometer using silver halide fiber optic technology so that the fibers are robust and flexible o Temperature range should be at least -80 to 180C o Pressure range should be at least vacuum to 69 bar (1,000 psi)
