Desorption atmospheric pressure photoionization.
Markus Haapala,Jaroslav Pól,Ville Saarela,Ville Arvola,Tapio Kotiaho,Raimo A. Ketola,Sami Franssila,Tiina J. Kauppila,Risto Kostiainen +8 more
TL;DR: An ambient ionization technique for mass spectrometry, desorption atmospheric pressure photoionization (DAPPI), is presented, and its application to the rapid analysis of compounds of various polarities on surfaces is demonstrated.

Comprehensive two-dimensional liquid chromatography–time-of-flight mass spectrometry in the analysis of acidic compounds in atmospheric aerosols
TL;DR: A novel method utilising comprehensive two-dimensional liquid chromatography interfaced to electrospray ionisation time-of-flight mass spectrometry was developed for the determination of organic acids in atmospheric aerosols.

Desorption and Ionization Mechanisms in Desorption Atmospheric Pressure Photoionization
Laura Luosujärvi,Ville Arvola,Markus Haapala,Jaroslav Pól,Ville Saarela,Sami Franssila,Tapio Kotiaho,Risto Kostiainen,Tiina J. Kauppila +8 more
TL;DR: Redirecting the DAPPI spray was observed to further improve the versatility of the technique: for dilute samples, parallel spray with increased analyte signal was found to be the best suited, while for more concentrated samples, the orthogonal spray with less risk for contamination is recommended.

Direct analysis of illicit drugs by desorption atmospheric pressure photoionization
Tiina J. Kauppila,Ville Arvola,Markus Haapala,Jaroslav Pól,Laura Aalberg,Ville Saarela,Sami Franssila,Tapio Kotiaho,Risto Kostiainen +8 more
TL;DR: The feasibility of desorption atmospheric pressure photoionization (DAPPI) in the direct analysis of illicit drugs was demonstrated by the analysis of confiscated drug samples of various forms such as tablets, blotter paper, and plant resin and bloom.
