| 摘要 |
The invention concerns a new method for quantifying particulate contaminants with increased reliability and that makes it possible to detect all particulate sizes according to standard ISO 14644-9. According to the invention, blowing/suction is done on a sampled surface S′, followed by a combination of analysis through optical counting of the suctioned particulate contaminants with a unit size below a value X2 and digital computation between two digital photos taken of the surface S′before and after blowing/suction, respectively, to quantify the particulates with a unit size above a value X1. |
