The WIBS-5/NEO is the world’s only instrument for real-time, single particle measurement of atmospheric bacteria, moulds, pollen, and other bioaerosols. WIBS-5 measures fluorescence to infer the presence of biological material in particles and provides detailed data on size, relative measure of shape, and fluorescent properties to enable classification of pollen, bacteria, and fungi.

Detailed Specs
The instrument is optimized for detection of bioaerosols, tryptophan, and NADH using two excitation wavelengths and two emission bands. Specific data for particles from 0.5 to 30 µm, as well as particle time-of-flight to detect coincidence; configurable to measure larger particles such as pollens and fungal spores. Enables selection of filter criteria for both full and partial measurements. Filter data using a wide variety of criteria: particle size, asymmetry, and concentration; fluorescent excitation and emission; or ratios of any of these parameters. Measurements and data on the ground or in the air.

WIBS-5/NEO Software
Two software packages are available for the WIBS-5: the standard software system and the WIBS Data Analysis Toolkit.
Standard Software
The WIBS-5/NEO graphical user interface features several components. The main window shown below details measured particles in real time and gives information on several housekeeping parameters.
