Abstract
|
The principle goal of this study was to investigate the use of MINICAM preconcentrator tubes (PCTs) as aerosol sampling devices. A series of penetration tests was conducted with a low-volatility liquid aerosol challenge on PCTs preloaded with several candidate sorbent bed materials. The results of this study show that commercial MINICAM PCTs were effective collectors for aerosol particles with aerodynamic diameters greater than 1 m; however, significant breakthrough occurred for sub-micron aerosols with all four sorbent materials tested. Based on these findings, the use of PCTs for aerosol sampling is acceptable over the restricted range of laboratory-generated aerosol challenges indicated in this report.
