1. A Raman analysis apparatus capable of real-time analysis while performing a chemical reaction experiment under elevated temperature and pressure conditions, the Raman analysis apparatus comprising:
a main body configured to accommodate a sample block filled with a sample, the main body including a channel and a window glass, the channel configured to inject a reaction solution into the sample block at a predetermined pressure such that the reaction solution reacts with the sample in the sample block, and the window glass on a side of the sample block such that the sample, which has reacted with the sample in the sample block, comes in contact with the window glass;
a reaction solution supplier configured to supply the reaction solution to the channel of the main body; and
a gas supplier configured to adjust a flow speed of the reaction solution in the channel by adjusting pressure in the channel by supply gas into the channel of the main body,
wherein a Raman probe is on an open side of the main body and is configured to emit a Raman laser toward the window glass, and
a temperature elevation unit is at the main body and is configured to elevate temperature,
wherein the sample block has a through-hole, the through-hole extending from one side to an opposite side of the sample block and filled with the sample, and
wherein the main body includes,
a first body including a first accommodation space, a main channel, a reaction solution channel, a gas channel, the first accommodation space having a groove shape and configured to accommodate a portion of the sample block, the main channel configured to communicate with the through-hole so that a reaction solution and gas flow into the through-hole of the sample block accommodated in the first accommodation space, the reaction solution channel configured to communicate with the main channel so that a reaction solution supplied from the reaction solution supplier flows through the reaction solution channel, and the gas channel configured to communicate with the main channel so that gas supplied from the gas supplier flows through the gas channel, and
a second body including a second accommodation space and the window glass, the second accommodation space being on a first surface of the second body facing a surface of the first body, on which the first accommodation space is provided, and having a groove shape to accommodate the other portion of the sample block, and the window glass being in an opening of an second surface, the second surface of the second body being opposite to the first surface of the second body in an accommodation direction of the sample block.
