The single parameter detection of temperature (H 2 O) is no longer sufficient for the absorption combustion diagnosis. There a huge demand simultaneous computed tomography (CT) diagnosis multi-parameters. This paper studied CO and NO, two representative products based on tunable diode laser spectroscopy (TDLAS) ultraviolet (UVAS). Different from research low limits, absorbance needs to be corrected in high-temperature high-pressure conditions due equipment performance CT system. A chamber...
The collinear long-short double-pulse laser-induced breakdown spectroscopy (LS-DP-LIBS) was employed in the detection of underwater copper samples. Discrete emission lines were obtained using LS-DP-LIBS with an appropriate delay between two pulses, while characteristic covered by continuous background and noise LIBS a single pulse. In condition LS-DP-LIBS, signal characteristics measured spectra at different experimental parameters including long-pulse width, lens-to-sample distance (LTSD),...
The long-short double-pulse laser-induced breakdown spectroscopy (LS-DP-LIBS) method was applied to qualitative and quantitative analyses of underwater steel samples improve the detection ability measurement. stable plasma intensity discrete emission lines were detected using LS-DP-LIBS when comparing measured results single-pulse LIBS (SP-LIBS) LS-DP-LIBS. long pulse produces a cavitation bubble without plasma, short induces within bubble. features for discussed in different intra-pulse...
Abstract The influence of resolution on spectral analysis is great significance to improve the measurement accuracy laser-induced breakdown spectroscopy (LIBS). In this study, low alloy steel samples were measured at different resolutions using a dual-channel spectrometer simultaneously determine plasma characteristics. diffraction efficiency grating was resolutions, which led intensities resolutions. affected LIBS analysis. For analysis, experimental results showed that Boltzmann plot...
