	abstract = {We have constructed, and tested as mass filters, linear quadrupoles with added hexapole fields of 4\%, 8\%, and 12\%, with and without added octopole fields. A hexapole field can be added to the field of a linear quadrupole by rotating the two y rods toward an x rod. This also adds an octopole field which can be removed by making the x rods greater in diameter than the y rods. In comparison to conventional quadrupole mass filters these rod sets have severely distorted quadrupole fields, with a mix of both even and odd higher spatial harmonics. They allow evaluating the performance of rod sets with strong geometric and field distortions as mass filters. Conventional mass analysis at the tip of the stability diagram has been compared to mass analysis using islands of stability. The stability islands are produced by applying an auxiliary quadrupole excitation field to the quadrupole. We show that with normal mass analysis at the tip of the stability diagram, the transmission, resolution, and peak shapes are relatively poor in comparison to a conventional rod set. However, the use of islands of stability dramatically improves the resolution and peak shape, and in some cases ion transmission, suggesting that mass analysis with islands of stability may provide a method to overcome a wide range of field imperfections in linear quadrupole mass filters.},

	abstract = {This paper demonstrates a method to isolate and characterise strong biogenic copper-binding ligands from an artificial seawater matrix. Pseudo-polarography is used to detect the ligands, determine their ionic strength-corrected binding constants, and track them through each step of the extraction process. Two ligand types are found, one strong and one relatively weak, with log K{\textquoteright} values of 49.4 +/- 1.1 and 19.8 +/- 5.5 respectively, assuming that the metal is bound as copper(II). If a copper(I) complex, the log K{\textquoteright} of the strong copper-binding ligand would be 25. Pseudo-polarography is then used to assess different resins for ligand extraction and to determine the eluent fraction in which the strong ligand is recovered. XAD-16 is found to be a suitable resin for extracting the strong binding ligand from salt water into methanol, suggesting that the ligand is weakly hydrophobic. As ligands are identified by their complexation of copper, no assumptions are made regarding the functional groups of these natural ligands. The copper-binding ligands are successfully extracted into solvents suitable for mass spectrometric analysis using soft ionisation methods such as electrospray and MALDI. (C) 2008 Elsevier B.V.

	abstract = {Formaldehyde cross-linking of proteins is emerging as a novel approach to study protein-protein interactions in living cells. It has been shown to be compatible with standard techniques used in functional proteomics such as affinity-based protein enrichment, enzymatic digestion, and mass spectrometric protein identification. So far, the lack of knowledge on formaldehyde-induced protein modifications and suitable mass spectrometric methods for their targeted detection has impeded the identification of the different types of crosslinked peptides in these samples. In particular, it has remained unclear whether in vitro studies that identified a multitude of amino acid residues reacting with formaldehyde over the course of several days are suitable substitutes for the much shorter reaction times of 10-20 min used in cross-linking experiments in living cells. The current study on model peptides identifies amino-termini as well as lysine, tryptophan, and cysteine side chains, i.e. a small subset of those modified after several days, as the major reactive sites under such conditions, and suggests relative position in the peptide sequence as well as sequence microenvironment to be important factors that govern reactivity. Using MALDI-MS, mass increases of 12 Da on amino groups and 30 Da on cysteines were detected as the major reaction products, while peptide fragment ion analysis by tandem mass spectrometry was used to localize the actual modification sites on a peptide. Non-specific cross-linking was absent, and could only be detected with low yield at elevated peptide concentrations. The detailed knowledge on the constraints and products of the formaldehyde reaction with peptides after short incubation times presented in this study is expected to facilitate the targeted mass spectrometric analysis of proteins after in vivo formaldehyde cross-linking.

	abstract = {This review presents our perspective on the state-of-the-art of atmospheric pressure photoionization (APPI) for LC/MS. Its focus is on APPI{\textquoteright}s capabilities and how to utilize them fully. The introduction includes a brief recounting of the history of APPI{\textquoteright}s development, as well as a summary of its operating principles and current position in the field. The primary ionization mechanisms in APPI are then addressed, including direct analyte photoionization (PI), dopant/solvent PI, and thermospray. Next a summary of the ion-molecule reaction pathways available for analyte ionization is presented, along with the conditions required for activating them. APPI{\textquoteright}s performance characteristics are then examined. in effect, this review is an interim report on progress made since Rafaelli and Saba concluded that "The ability... to direct the preferential ion formation towards one particular type...can be extremely useful for qualitative and quantitative determinations. For this purpose, a better insight in the processes involved in the ionization step is strongly needed" [A. Raffaelli, A. Saba, Mass Spectrom. Rev. 22 (2003) 318]. In the conclusion, we focus on areas of APPI technology identified as being either unoptimized or largely unexplored, and having the potential to be improved upon-the crux being that with further research and development improvements in the performance, capabilities, and ease-of-use of APPI may reasonably be anticipated.

Our results suggest that Raman sensing can serve as a viable non-invasive means to quantify tablet coating thickness in the presence of a fluorescent ingredient in the coating formulation (food colorant Alphazurine FG or D\&C Blue No. 4). This study comparatively tests the advantage of several data transformation approaches, including mean centering, standard normal variate, and Savitzky-Golay smoothed second derivative as means of improving predictive models in the presence of fluorescence. By application of the partial least squares (PLS) calibration algorithm to establish optimum covariance between transformed spectral data and measured tablet coating thicknesses, we have been able to create predictive models with calibration errors as small as 4 mu m for a training set that spans colored coating thicknesses from 50 to 151 mu m.

	abstract = {Liquid chromatography-tandem mass spectrometry (LC-MS/MS) has become the method of choice for the analysis of complex peptide mixtures. It combines the separation power of nanoflow LC with highly specific sequence analysis, allowing automated peptide sequencing with high resolution and throughput. For peptide fragmentation, the current experimental setup uses predefined parameters based on the mass-to-charge ratio of the individual precursor. Suitable parameters are typically established by empirical evaluation of fragment spectra of individual peptides used as standards. As a result, nonoptimal fragment spectra are obtained if peptides show fragmentation behavior different from these standards, which often result in the loss of sequence-specific fragment ion information. Here we describe a statistical approach for the systematic evaluation of the quality of individual peptide fragment spectra based on the calculation of their arithmetic mean and standard deviation. The method utilizes the dependence of these parameters on the difference in electric potential across the collision cell to determine the value that results in maximum information content. We show that the method is applicable to fragment spectra generated from a variety of multiply-charged tryptic peptides, over a wide concentration range, and on different types of mass analyzers. We also show how this novel approach can be used to define optimized collision energy settings over a wide mass-to-charge range.

	abstract = {The biomethylation of arsenic by the filamentous fungus Scopulariopsis brevicaulis is well documented, and the biomethylation of antimony by this fungus was recently established. However, in all the previous studies each metalloid was studied in isolation. Arsenic and antimony are often associated in the environment, and so an understanding of interactions between these elements is necessary. To this end, S. brevicaulis was grown in media containing mixtures of arsenic and antimony compounds in various proportions, and the principle nonvolatile biomethylation products (trimethylantimony and trimethylarsenic species) in the medium were quantified by using HG-GC-AAS. It was found that the yield of trimethylantimony compounds, obtained from the biomethylation of potassium antimony tartrate, was increased in the presence of sodium arsenite. The production of trimethylarsenic species from sodium arsenite was significantly inhibited in the presence of antimony (either as potassium antimony tartrate or antimony trioxide) at antimony concentrations too low to inhibit growth. This is although arsenic(III), in the absence of antimony, is much more readily biomethylated. That is 1.2-5.3\% of added arsenic is biomethylated by S. brevicaulis whereas only 0.0006-0.008\% of added antimony(III) is biomethylated over 1 month. Potassium hexahydroxyantimonate had no effect on arsenic biomethylation. The addition of potassium tartrate to cultures did not inhibit arsenic biomethylation. The biomethylation of sodium arsenate was not inhibited as much by antimony compounds. The inhibitory effect of antimony was found to be a function of the ratio of antimony to arsenic rather than the absolute amount of antimony.},

	abstract = {The use of directed support gas flows for the reduction in re-deposition of sputtered atoms in glow discharges has been investigated. In addition, various surface features of the bum spot obtained with a laboratory constructed jet-assisted glow discharge source have been studied using scanning electron microscopy and energy-dispersive X-ray analysis. The use of jets reduces re-deposition by a factor of three relative to static discharges improving the sampling efficiency for glow discharges, although significant redeposition occurs along the edge of the burn spot. It was also found that sample preparation can cause a higher incidence of bum spot cones and other surface structures which can reduce depth profiling resolution.},

Four different sizes of quartz tubes were compared with respect to spatial emission features for support gas and analyte species. Torches studied had the following inside dimensions: a 1-mm capillary tube with round cross section, a 2 x 4 mm tube, a 4 x 4 mm tube, and a 6 x 6 mm tube. Relative emission intensities of near-infrared lines for F, Cl, Br, I, C, N, and O atomic and ionic lines excited with the use of the He-CCP are tabulated. The detection limits range from 10 to 78 pg/s.},

	abstract = {Effects brought about by power and flow rate through the jets and pressure changes in a jet-assisted glow discharge source were studied. An increase in the power dissipated in the glow discharge increased both the sample sputtering and excitation of sputtered species in the negative glow. Although the application of the jets resulted in a similar increase in sample atomization, no uniform enhancement of emission intensities was observed. Instead, some emission lines were reduced in intensity, typically those characterized by relatively large absorption coefficients; while others were enhanced, those possessing relatively small absorption coefficients. This behaviour is suggestive of a self-absorption problem. Consequently, the most sensitive lines typically used for atomic emission analyses in glow discharges, resonance lines with large absorption coefficients, suffered from profound self-absorption with the application of the jets.},
