PURPOSE: To provide a safely structured probe which can surely prevent gas from being blown out to those of FT-IR and outside of system even if an ATR cell is broken down. CONSTITUTION: This probe device is provided with a probe 4 holding two internal optical passes 3a and 3b, holding an infrared ATR cell 2 being dipped in a reaction solution in a high pressure autoclave at its thp part, and installing a mounting flange 5 to the autoclave at the other end, and optically connecting an interval between the ATR cell 2 and the other end, and a pressure-proof window member 7 passing through infrared rays at low loss while resistible to the working pressure of the autoclave, respectively. In a state that the prove 4 is inserted into the autoclave, the pressure-proof window member 7 is superposed on a probe flange 5 and it is airtightly clamped to a nozzle of an autoclave vessel wall, the FT-IR at the outside of the autoclave and a detector and these optical passes 3a and 3b in an inner part of the probe 4 are optically connected together via the pressure-proof window member 7. |
