This short paper highlights a possible source of error in the use of personal samplers for airborne dust due to deposition of particles on the internal surfaces between the sampling orifice and the filters. Dust collecting cassettes, incorporating sampling orifice and filters, are proposed as a means of eliminating such errors. The benefits and drawbacks of using cassettes are discussed and experiments carried out to investigate their magnitude.
本文简短地强调了在使用空气传播灰尘的个人采样器时，由于颗粒沉积在采样孔和过滤器之间的内表面上可能产生的误差来源。文中提出采用包含采样孔和过滤器的集尘盒作为消除此类误差的一种方法。讨论了使用集尘盒的优缺点，并进行了实验以研究其误差大小。
