2.3 Three level scheme of laser induced fluorescence . Laser induced fluorescence (LIF) is a spectroscopy technique used for the detection of certain species. Laser light with wavelength 𝜆, corresponding to an excitation wavelength of the species under investigation, irradiates the gas sample.

Laser induced fluorescence (LIF) is a very sensitive technique for the species-selective spatially resolved detection of ground state atoms, which are the most populated state in a low

Laser induced fluorescence (LIF) is a very sensitive technique for the species-selective spatially resolved detection of ground state atoms, which are the most populated state in a low temperature plasma. LIF uses a single photon per excitation of the probed atom or molecule.

Laser Induced Fluorescence (LIF) is an optical spectroscopic technique where a sample is excited with a laser, and the fluorescence emitted by the sample is subsequently captured by a photodetector. LIF can be understood as a class of fluorescence spectroscopy where the usual lamp excitation is replaced by a laser source.

Laser-induced fluorescence (LIF) spectroscopy is of great importance for environmental monitoring. Besides outstanding sensitivity and good selectivity, particular advantages of the LIF technique include the capabilities for in situ analysis and remote sensing. The

Planar Laser-Induced Fluorescence, or PLIF, is an optical measurement technique based upon fluorescence emitted from chemical species excited by planar laser light. Essentially a sheet of laser light is passed through a flow field, and the subsequent fluorescence relaxation event is captured on a digital camera.

4-BPA is a phenoxyacetic acid, and a variety of analytical methods for phenoxyacetic acid detection have been developed, including capillary electrophoresis with laser-induced fluorescence , ultra-high liquid chromatography-mass spectrometry , headspace gas chromatography high-performance liquid chromatography and electrochemical methods [11,12

Laser-Induced Fluorescence (LIF) Fluorescent dyes (molecules) can absorb light at one frequency and subsequently re-emit (fluoresce) light at a different frequency. In experiments, the dyes are excited by laser light whose frequency closely matches the excitation frequency of

the fluorophores such as fluorescence life-time and ab-sorption cross-section, and the presence of lumines-cence quenchers in the water is relevant as well. Several publications5,6,8,9 report on fluorescence satura-tion of organic dyes in water. This technique, called spectroscopy of saturated fluorescence, makes use of

Laser-induced fluorescence detection is the most frequently applied detection technique on lab-on-a-chip devices. As most (bio)molecules of interest are not fluorescent, labeling is required

The research presented here aims at providing a deeper understanding of the formation of nitric oxide in diesel combustion. To this end, in-cylinder distributions of nitric oxide (NO) were acquired by laser-induced fluorescence (LIF) in a rapid compression machine at conditions representative of a modern diesel passenger vehicle.

Laser Induced Fluorescence (LIF) LIF imaging is a molecule specific visualization method with high spatial and temporal resolution. If the fluid itself contains no LIF-active species (like N2, CH4 or water), flow seeding with fluorescent markers (tracers) is used for scalar flow field imaging (Tracer-LIF). Laser imaging applications in fluid

Planar laser-induced fluorescence (PLIF) is an optical diagnostic technique widely used in fluid and gas applications. PLIF has proven to be a valuable tool for flow visualization as well as for quantitative whole-field measurements of concentration and temperature in liquid and concentration in gaseous flows.
