Liquid chromatography/mass spectrometry analyses were performed with an ion trap mass spectrometer (LCQ, Thermo Fisher Scientific Inc., MA) equipped with an HPLC system (Agilent, CA Model 1100) connected with a diode-array detector (DAD, G1315A). The sample solution (1-5 p,L) was applied on an Inertsil ODS-3 column (2.1 x 150 mm, 3 p,m, GL...

At least the three most intense lines (where available) are listed for each element. Some elements (e.g., Hg, S, P,) have their most intense lines in the vacuum UV region (< 190 nm) these hnes are not accessible on most commercial AAS systems.

Commercial DC arc emission spectrometers and commercial spark spectrometers are available as stand-alone laboratory instruments. This list is not comprehensive, but examples include a DC arc ClD-based EcheUe system from Thermo Elemental (www.thermoelemen-tal.com), a multiple polychromator spark system with PMT detectors from Spectro Analytical Instruments (www.spectro-ai.com), and a spark spectrometer polychromator system with PMT detectors from Jobin Yvon, Inc. (www.jyhoriba.com). Many instrument companies make portable spark instruments, some small enough to be handheld, for use in sorting metal alloys at scrap yards, confirming the identity of alloys received at loading docks. 

Products, Inc. in the form of extruded films and pellets. Solution cast films from l,l,l,3,3,3-Hexa-fluoro-2-propanol (used as received from Aldrich) solution, and thermo-compressed films (compressed at 230 C, 2000 pound per square inch, using 10 layers of as-received films) were prepared. Morphological characterizations indicate that the montmorillonite in these nylon 6 systems is extensively exfoliated (16,17).

Kim et alP described a sample pretreatment system for online determination of Pu using magnetic sector-ICP-MS with isotope dilution. They used a computer-controlled online sample preparation system (the PrepLab, Thermo Electron Corp., Winsford, UK) with Sr-Spec and TEVA-Spec resin micro-columns for Pu preconcentration. These resins, obtained from Eichrom Industries Inc. (Darien, Illinois, USA), were highly selective for radionuclide elements. To reduce the effect of the U H interference on Pu, a microconcentric nebuliser with integrated desolvation system (the MCN 6000, Cetac, Omaha, Nebraska, USA) was used as the sample introduction method. Using this approach, the authors were able to determine less than 10 pg of Pu in soil samples.
