A method for determination of PGE–Re concentrations and Os isotopic compositions in environmental materials
First comprehensive PGE and Re concentrations and Os isotopic compositions reported for BCR-723.
Determination of COREXIT components used in the Deepwater Horizon cleanup by liquid chromatography-ion trap mass spectrometry
Dispersants, like COREXIT, are used for oil spill cleanups. This analytical method could aid scientists in identifying specific dispersant mixtures.
Determination of spatial and temporal variability of pH and dissolved oxygen concentrations in a seasonally hypoxic semi-enclosed marine basin using continuous monitoring
Profiles of the Western Trough, Lough Hyne, show abrupt changes in measured pH values associated with stratification during seasonal hypoxia and anoxia.
An analytical method for quantifying petroleum hydrocarbon fractions in soils, and its associated uncertainties
This paper proposes a method for measuring total petroleum hydrocarbons (TPH) and other hydrocarbon fractions in soils, and discusses its uncertainties.
Use of core–shell nanoring amino-functionalized superparamagnetic molecularly imprinted polymer for matrix solid phase dispersion extraction and preconcentration of ultratrace levels of BPA from water samples
Determination of ultratrace levels of BPA in water by MSPD with a core–shell nanoring amino-functionalized magnetic molecularly imprinted polymer adsorbent followed by UFLC-MS/MS.
A solid phase extraction method for analysis of the iron–humic acid complex in natural water
A laboratory synthesized Fe-HA complex was used as a standard to develop a simple SPE method for analysis of Fe-HA complex in natural water.
Second-order chromatographic photochemically induced fluorescence emission data coupled to chemometric analysis for the simultaneous determination of urea herbicides in the presence of matrix co-eluting compounds
New second-order data from urea herbicides were studied. The method allows quantitation overcoming the interference from foreign species, in a short time and using minimal solvent volumes.
Portable micro-solid phase extraction for the determination of polycyclic aromatic hydrocarbons in water samples
This work describes for the first time the application of portable micro-solid phase extraction (μ-SPE) for the determination of polycyclic aromatic hydrocarbons (PAHs).
Paper
A formaldehyde trace gas sensor based on a thermoelectrically cooled CW-DFB quantum cascade laser
An adoptive de-noising technique based on Wavelet Transform and a zero-air based background subtraction technique have been successfully applied to improve the H2CO sensor performance, yielding sub-ppb measurement precision without reducing the fast temporal response.
Advancing the analysis of impurities in hydrogen by use of a novel tracer enrichment method
This paper presents and validates a novel hydrogen impurity enrichment method that can be used for concentrating the impurities in hydrogen to facilitate more routine and cost-effective purity analysis of fuel cell hydrogen.
