Patent ID: 7830505

Claim:
A spectroscopy analyzer for real-time diagnostics of process, comprising: a reactor of which an internal portion becomes a vacuum state; a detector for detecting a beam output from the reactor; and an analyzer for performing quantitative and qualitative analysis of a sample using an intensity of the detected beam; wherein the reactor comprises, an input window through which the beam is introduced; a receiving part in which the beam introduced through the input window is injected, and a reaction byproduct or a reactant is received temporarily so as to perform the real-time diagnostics of the reaction byproduct or the reactant; an output window through which the beam injected in the receiving part is output after being refracted and scattered by the reaction byproduct or the reactant; and a reflecting mirror which is provided in the receiving part, and reflects the beam introduced through the input window to be reciprocated at last once in the receiving part and then outputs the beam.
