In-situ measurements of spatially resolved spectroscopic data within a reactor chamber of a reactor

A system for in-situ spectroscopic measurements in heterogeneous catalytic reactors comprising:

• a reactor comprising a reactor chamber,
• a device for collecting optical radiation emitted by a sample inside the reactor chamber, wherein the device comprises a radiation guide for transmitting the optical radiation to a device for processing and displaying spectroscopic information arranged outside the reactor, and the radiation guide further comprises a tip situated in the reactor chamber configured to receive the optical radiation, and
• a sampling capillary having an orifice situated inside the reactor chamber for collecting a fluid sample inside the reactor chamber and an end situated outside the reactor chamber connected to an analytical device for at least one of quantitative and qualitative analysis
• wherein the radiation guide is configured such that the optical radiation is capable of entering and exiting the tip, and the tip is arranged within the sampling capillary proximal to the orifice.
