description The invention discloses a dust sampling method with a unique identifier. The method includes the steps that the initial weight of a blank filter membrane is weighed, meanwhile, the filter membrane and a filter membrane box are marked as a, and the filter membrane is installed on a sampling clamp; the sampling clamp with the filter membrane is loaded into a sampling instrument for dust sampling; after sampling is completed, the filter membrane a is taken down from the sampling instrument to be loaded into the filter membrane box a to be weighed; according to the weight weighed in the filter membrane box a, the dust weight is obtained compared with the initial weight of the blank filter membrane. Compared with a traditional dust sampling method, the problem of mark dismatching for man-made reasons is solved; meanwhile, mark matching preparation of the next time can be made in advance before the previous time of sampling is completed, so that time is effectively saved, and working efficiency is improved.
