PARTICLE SAMPLING AND MEASUREMENT IN THE AMBIENT AIR |
摘要 |
An apparatus and method for sampling and measuring air born particulate matter includes an inlet for the particulate containing gas to enter. A mechanism then removes coarse particles larger than a selected size while permitting filtered particles of less than the selected size to pass through. A chamber containing a quartz crystal sensor permits the filtered particles that have passed through to deposit to create an output signal in response to the deposited particle mass. |
