Support applied to testing of solid-state fluorescence samples

The invention relates to a support applied to testing of solid-state fluorescence samples. The support comprises a support sealing cover, a support body, a cuvette clamping ring, a clamping groove, a sample stage, a gas inlet guide pipe and a gas outlet guide pipe, wherein the support sealing cover and the sample stage are positioned on the top side and the tail side of the support body, respectively; the cuvette clamping ring penetrates through the support body to be fixed under the support sealing cover; a dihedral angle alpha between the plane of the sample stage and a horizontal plane is larger than 90 degrees and smaller than 180 degrees; the gas inlet and outlet guide pipes are arranged in the support body, and openings of the gas inlet and outlet guide pipes are formed above the sample stage and in the bottom of the support body, respectively. The sample support is a general solid-state fluorescence testing accessory, can be applied to an on-line fluorescence sensing test for gas in real time, and can
