Abstract:
A novel iminocoumarin precursor L was designed and well characterized. Sensor L showed high selectivity toward Pd(2+) in aqueous solution (CH3CN:H2O, v/v, 1:1) with a detection limit is 2.1 × 10(-7)M. Iminocoumarin was formed when added Pd(2+) to the solution of L by removing the propargylic group.

1.3K
Photoluminescence offers a wide range of applications due to its inherent sensitivity and selectivity. This technique allows for both direct and indirect analyses of the analyte. Direct quantitative analysis is possible when the analyte exhibits a favorable quantum yield for fluorescence or phosphorescence. However, an indirect analysis may be feasible if the analyte is not fluorescent or phosphorescent, or if the quantum yield is unfavorable. Indirect methods include reacting the analyte with...

In gas chromatography, different detectors are employed to meet specific analytical needs. These detectors are often categorized based on their detection mechanisms and the types of compounds they are best suited to analyze. Thermal Conductivity Detectors (TCD), Flame Ionization Detectors (FID), and Electron Capture Detectors (ECD) represent common categories, each with unique operating principles and applications. However, beyond these, several other detectors are designed for more specialized...
