Fast analysis of particulate materials represents one of the most

challenging issues at the forefront of current analytical chemistry. The

ability to rapidly analyze particulate materials, including aerosols,

hydrosols and powders, may have far-reaching consequences and impact on

the environmental sciences, on industrial process control, and on human

health. Although analysis of particulate materials has been a long

desired goal, it could not be achieved satisfactorily by most of the

previously known methods. It is therefore necessary to develop new

approaches for solving these problems. The methods recently developed

for this specific purpose include Fourier Transform (FT) Chemical

Imaging, Modified Laser Induced Breakdown Spectroscopy, Fast Conductance

Laser Multiphoton Ionization, Laser Induced Fluorescence and Cavity

Ringdown Spectroscopy. The methods and some of the results related to

environmental and security applications will be presented.
