| Abstract: | When aerosol is sampled by a particle counter in cleanroom,it has some sampling error,inclusive of non-isokinetic sampling error,deposition sampling error in a sampling tube,counting error and error of sampling rate in a particle counter which is -5%,-3%,-3.5% and ±3% respectively.It can result in a compositive error about 7.2% in a particle counter. |
