Feb 24, 2014 · In this study, the conventional method generally employed for PBAP sampling and analysis (automatic volumetric trap) was co-located with a WIBS-4 instrument at a rural site and an urban location. Results from both instrumental methods were compared and contrasted.

Dec 1, 2012 · A Bioaerosol sensing instrument referred to as WIBS-4, designed to continuously monitor ambient bioaerosols on-line, has been used to record a multiparameter “signature” from each of a number of Primary Biological Aerosol Particulate (PBAP) samples found in air.

In this study, the Wideband Integrated Bioaerosol Sensor (WIBS) 4+ model was evaluated for its ability to sample and detect ambient fungal spore and pollen concentrations, compared to the traditional Hirst volumetric method.

May 1, 2012 · One instrument designed for this purpose, known as WIBS-4, can measure individual particles and their number-size distributions in two pre-defined size ranges: (i) ∼0.3–12 μm and (ii) ∼3–31 μm (optical diameter, polystyrene latex equivalent) while also making measurements of fluorescence across two wavebands.

Fluorescent biological aerosol particles measured with the Waveband Integrated Bioaerosol Sensor WIBS-4: laboratory tests combined with a one year field study, Toprak E., and Schnaiter M., Atmospheric Chemistry and Physics, 13, 225–243, 2013 (doi:10.5194/acp-13-225-2013)

In this paper bioaerosol measurements conducted with the Waveband Integrated Bioaerosol Sensor mark 4 (WIBS-4) are presented. The measurements comprise aerosol chamber characterization experiments and a one-year ambient measurement period at a semi-rural site in South Western Germany.

The WIBS-4 prototype measures particle sizing using a dual gain detection approach; the high gain is used for monitoring smaller size particles (0.5–12 µm) and the low gain detects larger size particles (3–31 µm).

Sep 15, 2024 · Ambient fluorescent aerosol particles (FAP) were monitored using the WIBS-4+ which operates on the basis of light induced fluorescence. The WIBS-4+ is a modified version of the WIBS-4 model that was developed by the University of Hertfordshire.

Dec 19, 2024 · How WIBS Works. WIBS identifies airborne bioaerosols by shining ultraviolet (UV) light on particles in the air. This light makes certain biological molecules (e.g. amino acids), like those in bacteria, spores and pollen, fluoresce. WIBS measures this …
