The collection of solid particulates and liquids from surfaces by the use cloth swipes is fairly ubiquitous. In such methods, there a continuous concern regarding ability to locate quantitatively sample analyte species material. this effort, we demonstrate initial coupling an Advion Plate Express plate reader liquid sampling-atmospheric pressure glow discharge (LS-APGD) microplasma ionization source with Orbitrap mass spectrometer perform uranium isotopic analyses solution residues on cotton...
The spatial distributions of elemental and molecular species are vital pieces information for a broad number applications such as material development bio/environmental analysis. There is currently no single analytical method that can simultaneously acquire elemental, molecular, from sample. This paper presents the coupling an NWR213 laser ablation (LA) system to liquid sampling-atmospheric pressure glow discharge (LS-APGD) microplasma combined atomic (CAM) work demonstrates fundamental...
The operational parameters of the AD-LS-APGD-OES microplasma have been evaluated in terms understanding their roles analyte response.
The use of LS-APGD-MS is demonstrated for applications in cell culture media analysis and validated by ICP-OES. Use simple polymer fiber injector loop allows determinations the relative free<italic>vs.</italic>bound fractions metals.
A practical method for preparation of solution residue samples analysis utilizing the ambient desorption liquid sampling-atmospheric pressure glow discharge optical emission spectroscopy (AD-LS-APGD-OES) microplasma is described. Initial efforts involving placement aliquots in wells drilled into copper substrates, proved unsuccessful. design-of-experiment (DOE) approach was carried out to determine influential factors during sample deposition including volume, solute concentration, number...
