The utility model relates to an online pre-treatment device of a Raman spectrometer and a system thereof, wherein a sample to be detected is pre-treated before the Raman spectrum detection instrument detects the sample in a PX (paraxylene) device; reaction jars for absorption treatment are adopted to perform absorption and removal of impurities on the sample to be tested; at least two reaction jars for the absorption treatment are employed for absorption and sweeping, so that the whole pre-treatment process is not influenced by the absorption saturation degree of the reaction jars for the absorption treatment, and can be continued without interruption. The online pre-treatment device provided by the utility model has the advantages of high recovery rate, low cost, less investment, no pollution and the like; and both the process for field sample collection, cooling treatment and removal of unsaturated hydrocarbon, and the process for treating recovered samples are taken into consideration. The online pre-treat
