Comparative particulate sampling methods
… determining the mass concentration of suspended particulate matter in ambient air. Most of these methods, including the EPA reference method, require manual filtering and weighing of the collected sample. This is both costly and time-consuming and is subject to a considerable amount of human …

Indicators of Mold Growth in Indoor Environments
… of investigating airborne fungi by traditional particulate sampling techniques. VOCs and carbon dioxide are both examined in order to evaluate their usefulness as possible metabolic indicators of mold growth. A specially designed purge and trap laboratory setup was built and operated for the …

Determination of Size Fractions and Concentrations of Airborne Particulate Matter Generated From Construction and Demolition Waste Processing Facilities
… of these processes is the generation of particulate matter.This study involved quantifying and qualifying airborne particulates at three C&D processing facilities. Active stationary particulate sampling devices were employed to quantify the particle sizes of interest. Results were …

Analytical and experimental analysis of fireplace performance
A preliminary fireplace design to reduce particulate, carbon monoxide, and unburned hydrocarbon emissions has been fabricated and tested. Using a damper and glass pane, the design solves the problem of uncontrolled air entering the firebox. The pane reduces the inlet area and directs the flow of …

A Series of Studies to Support and Improve DPM Sampling in Underground Mines
Diesel particulate matter (DPM) is the solid portion of diesel exhaust, which occurs primarily in the submicron range. It is complex in nature, occuring in clusters and agglomerated chains, and with variable composition depending on engine operating conditions, fuel type, equipment maintenance, …

Pneumatic Particulate Collection System Analysis and Design
A pneumatic particulate collection system harnesses the energy associated with the release of a compressed gas to transport particulate to a collection chamber. In an effort to improve the efficiency of a previously designed collection system, high speed imaging in conjunction with computational …
