NOVELTY - The utility model claims a graphene-based enhanced infrared absorption device, the device comprises a substrate, a side wall, a top wall, a graphene film, a micro-structure layer, a micro-structure layer formed by micro-structure of periodic arrangement, the substrate, a side wall and a top wall forming the micro flow passage, the graphene film and micro-structure layer in the micro flow channel, the number of micro-structure layer is more than two layers, the graphene film is placed on each micro-structure layer. when it is used, micro-flow channel flows in the liquid to be measured by infrared absorption spectrum test substance contained in the liquid to obtain the substances of the chemical components and structure information. As the infrared absorbing multilayer graphene film enhances the substance contained in the liquid, the utility model has high sensitivity and so on.
