“…In more advanced prototypes, to excite fluorescence, two wavelengths (266, 355 nm) have been used [ 32 , 33 ] or the entire spectrum measured [ 34 ]. In the following years, further analyzers were built using the LIF method for the detection of biological analyzers [ 35 , 36 ]. So far, the most technologically advanced instrument is the LIF instrument, which uses fluorescence lifetime measurements in four spectral ranges using two excitation wavelengths (293 and 337 nm) [ 37 ].…”

“…This approach ensures continuous measurement and immediate response. Thus the analysis process can be facilitated and accelerated compared with other commonly used analytical procedures (Hill et al, 1999;Choi et al, 2014;Taketani et al, 2013;Feugnet et al, 2008). Besides advantages such as reagentless and real-time particle characterization, laser-based methods do not provide information on the chemical composition of aerosol.…”

“…Various analytical methods of particle discrimination and classification have been applied. It has been shown that principal component analysis (PCA), linear discriminant analysis (LDA) and hierarchical cluster analysis (HCA) of fluorescence spectra greatly increase the discrimination of particles compared with methods based on spectra averaging or fluorescence threshold Kaliszewski et al, 2013;Pan et al, 2012;Savage et al, 2017;Crawford et al, 2015). Artificial neural networks (ANNs) comprise an emerging analytical approach that is becoming more widely and successfully applied in various life domains such as chemical analysis (Borecki et al, 2008), image recognition (Antowiak and Chałasińska-Macukow, 2003), data mining and weather forecasting (Purnomo et al, 2017).…”

“…Initially the LIF based detection of airborne particles was developed for military applications and covered stand-of (LIDARS) and "in situ" devices which detect individual particles in flowing air (Choi, Ha, Lee, & Lee, 2014;DeFreez, 2009;Farsund, Rustad, & Skogan, 2012;Feugnet et al, 2008;Ho, 2002;Ho & Duncan, 2005;Jeys, Herzog, Hybl, Czerwinski, & Sanchez, 2007;Kaliszewski et al, 2013;Saari, Reponen, & Keskinen, 2014;Sivaprakasam, Huston, Scotto, & Eversole, 2004;Wojtanowski et al, 2015). Recently, many reports have described civilian applications of continuous, real-time fluorescence flow detectors including monitoring of pollens or determining air quality in a classroom and a hospital environment.…”
