Abstract: The present invention relates to an integrated optical measurement device. The integrated optical measurement device includes a light source module that includes first to Nth light source units each of which irradiates light of different wavelengths to a sample (N is a natural number greater than or equal to 2), when a direction in which the light source module irradiates light is downward, a detection module that is provided above the light source module to detect a reaction of the sample, a sample unit that is provided below the light source module to fix the sample, and an angle mount that fixes the first to Nth light source units at a predetermined angle, in which the first to Nth light source units are fixedly installed around the detection module.

Abstract: The present invention relates to a technology for manufacturing a nanocomposite membrane comprising a graphene oxide coating layer with a thickness of 1 nm to 50 nm, which is formed on various supports and has nanopores, and a reduced graphene oxide nanocomposite membrane, and applying the membranes to gas separation. The graphene oxide nanocomposite membrane for gas separation of the present invention has excellent gas permeability and selectivity at the same time, and especially, excellent hydrogen gas permeability and hydrogen gas selectivity compared with carbon dioxide, and the reduced graphene oxide nanocomposite membrane has remarkably enhanced hydrogen gas permeability and hydrogen gas selectivity compared with carbon dioxide, and thus the membranes are applicable as a gas separation membrane in an industrial field involving a hydrogen separation process.
