Investigations into a novel method for atmospheric polycyclic aromatic hydrocarbon monitoring.
A novel analytical method for atmospheric polycyclic aromatic hydrocarbons (PAHs) was developed based on laser induced fluorescence (LIF) of samples on quartz multi-channel polydimethylsiloxane traps. A tunable dye laser with a frequency doubling crystal provided the excitation radiation, and a double monochromator with a photomultiplier tube detected emitted fluorescence. The method allowed fo...
متن کاملLaser-induced fluorescence of NCN in low and atmospheric pressure flames.
The cyanonitrene radical, NCN, is detected by laser-induced fluorescence in laminar, adiabatic, flat phi=1.3 methane-air flames at 200 hPa and atmospheric pressure. Laser excitation of the A approximately 3Piu(020)-X approximately 3Sigmag-(000) band at 317 nm allows off-resonant fluorescence to be detected at 326 nm. Excitation and dispersed fluorescence spectra are presented, as well as profil...
متن کاملHigh-sensitivity instrument for measuring atmospheric NO2.
We report on the development of a high-sensitivity detection system for measuring atmospheric NO2 using a laser-induced fluorescence (LIF) technique around 440 nm. A tunable broad-band optical parametric oscillator laser pumped by the third harmonic of a Nd:YAG laser is used as a fluorescence excitation source. The laser wavelength is tuned at peak and bottom wavelengths around 440 nm alternati...
متن کاملViolet (405 nm) diode laser for laser induced fluorescence detection in capillary electrophoresis
The first application of the violet diode laser for laser induced fluorescence (LIF) detection in capillary electrophoresis is reported. Operating at 405 nm with an output power of 5 mW, this laser offers many advantages over conventional red diode lasers operating at 635 nm. We demonstrate the suitability of the violet diode laser for LIF detection by detecting amino acids labeled with naphtha...
متن کاملOptical Diagnosis of Pulsed Streamer Discharge under Atmospheric Pressure
This paper introduces recent optical measurements of radicals in atmospheric pressure non-thermal plasma. Laser-induced fluorescence (LIF), laser absorption, and optical emission spectroscopy (OES) techniques have been applied for density and temperature measurements of OH radicals, NO molecules, ozone, atomic oxygen, atomic nitrogen, and N2( A3Σ u ) metastables in pulsed corona and pulsed diel...
