3) excitation-emission matrix spectrofluorimetry 激发发射矩阵荧光法 1. In this study, TYR and TRY in amino acid oral liquid were resolved simultaneously and determined directly by using second-order calibration based on alternating trilinear decomposition algorithm and excitation-emission matrix spectro...
Excitation emission matrix (EEM) and cavity ring-down (CRD) spectral signatures have been used to detect and quantitatively assess contamination of jet fuels with aero-turbine lubricating oil. The EEM spectrometer has been fiber-coupled to permitin situmeasurements of jet turbine oil contamination of...

Excitation-emission matrix (EEM) fluorescence spectroscopy has been widely used to characterize dissolved organic matter (DOM) in water and soil. However, interpreting the > 10,000 wavelength-dependent fluorescence intensity data points represented in EEMs has posed a significant challenge. Fluorescence ...
Fluorescence excitation–emission matrix (EEM) spectroscopy has been widely used to investigate the composition and biogeochemical cycling of DOM due to its simplicity and sensitivity [8]. Several studies have characterized leachate DOM through EEM spectral analysis: Baker and Curry [9] investigated the...
Each excitation-emission matrix (EEM) data set of nitrified and non-nitrified water samples were successfully decomposed into a three component PARAFAC model (C-1, C-2, and C-3). The spectral shapes of these components were compared with those identified earlier in other studies from the ...
Fluorescence regional integration (FRI) was used to measure changes in cumulative regional intensity of five operationally defined regions from excitation-emission matrices (EEM) subsequent to chlorination. The chan...关键词: excitation-emission matrix (EEM) DBP formation chlorine fractionation NOM ...
The method is based on immersing a small piece (2 cm(2)) of anion exchange membrane into 5 mL of solution or soil paste for 30 minutes, after which the membrane is removed, rinsed, and wiped dry. The...doi:10.2136/sssaj2017.06.0188Oshri Rinot...
