Cantilever-enhanced photoacoustic measurement of light-absorbing aerosols
Juho Karhu, Joel Kuula, Aki Virkkula +3
Photoacoustic detection is a sensitive method for measurement of light-absorbing particles directly in the aerosol phase. In this article, we demonstrate a new sensitive technique…
Electromagnetic Radiation Detection with Broad Spectral Sensitivity and Large Dynamic Range using Cantilever-based Photoacoustic Effect
Sucheta Sharma, Toni Laurila, Jussi Rossi +4
A sensitive photoacoustic detection approach employing a silicon cantilever is investigated for power measurement of electromagnetic radiation. The technique which is actuated by p…
Photoacoustic characteristics of carbon-based infrared absorbers
Jussi Rossi, Juho Uotila, Sucheta Sharma +5
We present an experimental comparison of photoacoustic responsivities of common highly absorbing carbon-based materials. The comparison was carried out with parameters relevant for…
Sub-part-per-trillion level detection of hydrogen fluoride by cantilever-enhanced photo-acoustic spectroscopy
Teemu Tomberg, Markku Vainio, Tuomas Hieta +1
We present a highly sensitive hydrogen fluoride detector based on simple cantilever-enhanced photo-acoustic spectroscopy. A noise equivalent concentration of 5 parts-per-trillion w…
