Dilution versus fractionation: Separation technologies hyphenated with spICP-MS for characterizing metallic nanoparticles in aerosols

Jian Wang, Christian Ludwig, Andrea Testino, Tianyu Cen

The presence of metal salts has become one of the major limitations for measuring metallic nanoparticles (NPs) in single particle inductively coupled plasma mass spectrometry (spICP-MS). Their presence generates a background signal in spICP-MS that can be ...

Siloxane compounds in biogas from manure and mixed organic waste: Method development and speciation analysis with GC-ICP-MS

Christian Ludwig, Debora Foppiano, Mohamed Tarik

A novel method for the determination of linear and cyclic siloxane compounds (L2, L3, D3, D4, D5, and D6) in biogas was developed by combining gas chromatography (GC) with inductively coupled plasma mass spectrometry (ICP-MS). Using a continuous liquid que ...

Direct determination of niobium at the low nanogram level in mineral waters and freshwaters

Michaël Bensimon, Montserrat Filella, David-Julien Magnenat

The increasing use of elements such as Nb and Ta in green and information technologies makes it necessary to develop appropriate analytical methods for studying their environmental and ecotoxicological behaviour. This paper describes the first time Nb has ...

Least-Squares Fitting of Time-Domain Signals for Fourier Transform Mass Spectrometry

Yury Tsybin, Anton Kozhinov, Tagir Aushev

To advance Fourier transform mass spectrometry (FTMS)-based molecular structure analysis, corresponding development of the FTMS signal processing methods and instrumentation is required. Here, we demonstrate utility of a least-squares fitting (LSF) method ...

Biogenic and biomass burning organic aerosol in a boreal forest at Hyytiala, Finland, during HUMPPA-COPEC 2010

Satoshi Takahama, Wuzhou Song

Submicron aerosol particles were collected during July and August 2010 in Hyytiala, Finland, to determine the composition and sources of aerosol at that boreal forest site. Submicron particles were collected on Teflon filters and analyzed by Fourier transf ...

Development and Application of Devices for Online Trace Element Analysis of Thermal Process Gases from Woody Feedstocks

Marco Wellinger

When using natural or waste wood in thermo-chemical conversion processes, the presence of a number of heteroatoms (e.g. sulfur, chlorine, potassium and sodium or heavy metals) may hinder the processes themselves as well as pose a threat to equipment and/or ...

Lowering the detection limit for arsenic: Implications for a future practical quantitation limit

Janet Gordon Hering

The practical quantitation limit (PCIL) for arsenic (As) is currently orders of magnitude higher than its nonenforceable, health-based standard in California. Analytical limitations caused by chloride (CO interference can be overcome using high-resolution, ...

ELNES at magic angle conditions

Cécile Hébert

If one needs to cancel the effects of the anisotropy of the sample in a EELS experiment in the TEM, a particular couple of values for the collection and convergence angle must be used, called magic angle conditions (MAC). Recent developments in the theory ...

On an exact analytical solution of the Boussinesq equation

Marc Parlange

A useful exact analytical solution of the Boussinesq equation is discussed and is the most general solution presently available, and in particular yields a solution for a finite aquifer. It provides insight into the physical processes arising during the ex ...
