SURFACE-DEPOSITED PARTICLE AND SUBSTANCE SAMPLING, DILUTION AND ANALYSIS DEVICE

摘要

The present invention is related to providing a device for sampling, diluting and analyzing particles and substances normally located on surfaces, wherein said device comprises a collection system which, through a rotating collecting surface and a scraper gather the sample. The device also comprises a tank-like storage system to store the diluting solution and a dilution chamber that permits the sample to mix with the solution and be diluted. This mixture is subsequently placed in contact with a detection system which is capable of discerning the presence or not of the substance being sampled.
