    Dissolved organic matter and trace metals in solid-phase extracts of water samples from the Elbe-Weser estuary (2018)
    PANGAEA
    In:  Supplement to: Ksionzek, Kerstin B; Zhang, Jing; Ludwichowski, Kai-Uwe; Wilhelms-Dick, Dorothee; Trimborn, Scarlett; Jendrossek, Thomas; Kattner, Gerhard; Koch, Boris P (2018): Stoichiometry, polarity, and organometallics in solid-phase extracted dissolved organic matter of the Elbe-Weser estuary.

    Description: Water samples were either acidified to pH 2 or processed without acidification (pH 8) prior solid-phase extraction (SPE). SPE was performed in quadruplicates. Thus, the given concentrations and elemental ratios of solid-phase extracts are average values of quadruplicate measurements (+/- standard deviation). Some values for SPE-V and SPE-As were below limit of detection (LOD).

    Enhanced analysis of stratified climate archives through upgrade of Laser Ablation Inductively Coupled Plasma Quadrupole to Time of Flight Mass Spectrometry? (2010)

    Description: ICP-MS, Time of Flight, laser ablation, solid and liquid samples, ice cores, Antarctica, mineral dust, trace element analysis. - The analysis of the inorganic composition of climatic archives provides proxies for climate reconstruction. For many applications commercially available inductively coupled plasma quadrupole mass spectrometry (ICP-Q-MS) systems are used for investigations. One aim of this thesis was to test the laser ablation (LA)-ICP-Q-MS method for the analysis of different sample matrices (polar ice cores, bivalves, frozen lake sediment cores). The main limitation of LA-ICP-Q-MS measurements is the number of analysed isotopes, especially for point scan analysis of embedded particles in the ice matrix and the analysis of growth bands of bivalve shells. Analysing as many isotopes as possible is of interest to deduce e.g. the corresponding source region of embedded particles in the ice matrix. The quasi-simultaneous detection of several isotopes of transient signals is realised in ICP-Time of Flight-MS (ICP-TOF-MS) systems. The applicability of the newly developed ICP-TOF-MS system for ice core analysis in climatic research was explored in this thesis. With the present experimental setup the analysis of trace elements in ice core samples is only possible for liquid samples. The accuracy and precision compares to well established ICP-Q-MS systems. Using the Aridus II as sample introduction system the signal sensitivity was 2-10 times lower for the ICP-TOF-MS compared to ICP-Q-MS systems. Calibration studies and investigation of reference materials showed that the calibration range is limited to an order of magnitude of about 10exp4 to 10exp5 except for m/z ratios between 23 amu and 72 amu where it is even lower. The observed ...
