BUOYANCY-CORRECTED GRAVIMETRIC ANALYSIS SYSTEM |
摘要 |
<p>Relatively accurate gravimetric analysis of airborne particulate matter in a sample is achieved by making gravimetric measurements of the sample on a microbalance in a closed chamber, continuously electronically monitoring air pressure, humidity and temperature in the chamber, continuously controlling humidity and temperature in the chamber, and combining the gravimetric measurement with measurements of air pressure, humidity and temperature in the chamber to make a buoyancy corrected determination of the mass of the particulate matter.</p> |
