Membrane-based detection of lead ions in seawater, urine and drinking straws through laser desorption/ionization

Application of flowerlike MgO for highly sensitive determination of lead via matrix‐assisted laser desorption/ionization mass spectrometry

“…It is much lower than the United States Environmental Protection Agency permitted lead level in drinking water (∼72 nM). We compared the sensitivity for lead by NEDC‐assisted LDI, MgO/NEDC‐assisted LDI, MgO as absorbent, nanogold membrane LDI by Liu et al and ICP‐MS method. The results are listed in Supplementary Table S2.…”

Simple distance-based thread analytical device integrated with ion imprinted polymer for Zn2+ quantification in human urine samples

“…Several effective methods have been developed for Zn 2+ determination, including atomic absorption spectroscopy, 16 gamma spectrometry, 17 immunochromatographic assay, 18 inductively coupled plasma mass spectrometry (ICP-MS), 19 inductively coupled plasma optical emission spectroscopy (ICP-OES), 20 atomic fluorescence spectrometry, 21 stripping voltammetry, [22][23][24] differential pulse voltammetry, 25 potentiometric methods, 22,26,27 chronopotentiometry analysis, 28 light scattering, 29 laser-induced breakdown spectroscopy, 30 laser desorption/ionization mass spectrometry (LDI-MS) 31 and chro-matographic techniques (HPLC). 32 Even though these methods provide high sensitivity and selectivity for Zn 2+ monitoring, they are also limited for point of care (POC) testing owing to their large size and higher cost of analysis and time.…”

Review—Recent Advances in Electrochemical Sensing of Lead Ion

“…A variety of analytical methods can achieve the detection of Pb 2+ . Some conventional analytical methods, such as colorimetry, 10 inductively coupled plasma analysis, 11,12 atomic absorption spectrometry, 13 high-performance liquid chromatography 14 and mass spectrometry 15 have been widely used in its detection field. These analytical methods can accurately detect the concentration of Pb 2+ .…”
