Abstract

The present disclosure relates to a gas purification apparatus and a trace substance detection device. The gas purification apparatus includes a first purification component, a second purification component and a switching component, wherein the switching component can be switched between a first state and a second state, the first purification component and a component to be purified form a gas purification loop in the first state, and the second purification component can provide a regeneration gas for the first purification component in the second state, so that water vapor and impurities in the first purification component are discharged to outside. In the gas purification apparatus, the filtered air is used as the regeneration gas to prevent secondary pollution in a recycling process of the purificant; furthermore, by means of the state switching function of the switching component, the mutual interference between the two working states of purification and regeneration can be prevented, and all the above advantages can improve the reliability of the recycling of the purificant, thereby optimizing the performance and the service life of the gas purification apparatus.
