    摘要: A personal dust sampler, for example to be carried on the lapel of a wearer, has a body part with a gas entry protruding therefrom. The entry has an aspiration efficiency of approximately unity for the gas flow rate of a pump (not shown) which is attachable to an exit from the body. Mounted inside the body is a filter which is removable for examination after a sampling period.
