Characterization of Undigested Particulate Material Following Microwave Digestion of Recycled Document Papers

Autor: David W. Szymanski, Ruth Waddell Smith, Elizabeth A. McGaw

Publikováno v: Journal of Forensic Sciences. 54:1171-1175

Recycled document paper was microwave digested in a solution of HNO(3) and H(2)O(2) prior to analysis by inductively coupled plasma mass spectrometry (ICP-MS) to determine the trace elemental concentrations within the paper. Undigested particulate ma

Determination of Trace Elemental Concentrations in Document Papers for Forensic Comparison Using Inductively Coupled Plasma-Mass Spectrometry

Autor: Elizabeth A. McGaw, Ruth Waddell Smith, David W. Szymanski

Publikováno v: Journal of Forensic Sciences. 54:1163-1170

With improvements in manufacturing procedures, comparing physical characteristics of paper samples may not offer sufficient discrimination among different vendors. In this work, the potential to differentiate paper samples based on trace element conc

A comparison of boron-doped diamond thin-film and Hg-coated glassy carbon electrodes for anodic stripping voltammetric determination of heavy metal ions in aqueous media

Autor: Elizabeth A. McGaw, Greg M. Swain

Publikováno v: Analytica Chimica Acta. 575:180-189

The performance of boron-doped diamond (BDD) for the anodic stripping voltammetric (ASV) determination of heavy metal ions (Zn2+, Cd2+, Pb2+, Cu2+, Ag+) was compared with that of Hg-coated glassy carbon (Hg-GC). Hg has historically been the electrode

Metal ion analysis in contaminated water samples using anodic stripping voltammetry and a nanocrystalline diamond thin-film electrode

Autor: Yoshiyuki Show, Elizabeth A. McGaw, Greg M. Swain, Prerna Sonthalia

Publikováno v: Analytica Chimica Acta. 522:35-44

Boron-doped nanocrystalline diamond thin-film electrodes were employed for the detection and quantification of Ag (I), Cu (II), Pb (II), Cd (II), and Zn (II) in several contaminated water samples using anodic stripping voltammetric (ASV). Diamond is

Pressurized liquid extraction of diesel and air particulate standard reference materials: effect of extraction temperature and pressure

Autor: Stephen A. Wise, Elizabeth A. McGaw, Michele M. Schantz

Publikováno v: Analytical chemistry. 84(19)

Four particulate matter Standard Reference Materials (SRMs) available from the National Institute of Standards and Technology (NIST) were used to evaluate the effect of solvent, number of static cycles and static times, pressure, and temperature when

Comparison of orthogonal liquid and gas chromatography-mass spectrometry platforms for the determination of amino acid concentrations in human plasma

Autor: Mark S. Lowenthal, Elizabeth A. McGaw, Karen W. Phinney

Publikováno v: Journal of chromatography. A. 1217(37)

Concentrations of amino acids in a human plasma pool were determined using four independent quantification methods. Orthogonal separation schemes (LC, GC, or GC x GC) and detection systems (triple quadrupole or time-of-flight mass spectrometry) are s
