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)
