| This work describes the use of porous membranes to capture aerosolized and water-based spores for detection by IR spectroscopy. The key aspect of this work is to render the porous membranes amenable for direct analysis by IR transmission or reflection methods. In our work we have used different varieties of membranes such as metallic (silver), anodic disc and polymer membranes. The advantages and disadvantages of the various membranes along with details of the sampling procedures and chemometric approaches to achieve high detection sensitivity and selectivity will be discussed. |
