The invention relates to a solid sampling-non-dispersion atomic fluorescence photometer collocating device and an analyzing method. The device comprises a solid sampler, an integrated interface, a sample pipe, a peristaltic pump, a tee joint, a gas-liquid separator, a detector and a computer. The method comprises the following steps of: volatilizing an analyzing element in a volatile halide way and absorbing by absorption liquid by adding an auxiliary heat release agent or an ashing auxiliary agent in the solid sampler. The absorption liquid is introduced into a chemical steam generating system for reacting with potassium borohydride (sodium); and the generated volatile hydride or atomic steam is carried into an instrument atomization area for being detected by atomic fluorescence. The invention directly adopts solid sampling, rapidly realizes the detection of toxic elements, such as arsenic, stibium, selenium, mercury, and the like in the samples, such as geology, environment, food, biology, and the like and has the advantages of higher analyzing speed, low analyzing cost, high detecting sensitivity, high device portability, environmental protection, and the like.
