“…The mass spectra were recorded at 3 scans s −1 under electron impact at 70 eV and mass range 140-410 amu (Čvančarová et al, 2012). The most relevant detectable congeners of PCBs were quantified regarding the presence of Delor 103, as well as the most toxic and commonly monitored congeners (Olšovská et al, 2010;European Standard, 2008).…”

“…PCBs have been produced for many years and employed as dielectric fluids and additives, but due to their toxicity, they have been banned during the 70s (Llobet et al, ). Nevertheless, PCBs concentration in marine matrices is still relevant owing to their persistence, pronounced lipophilicity and bioaccumulation (Olšovská et al, ). Dissolved PCBs in seawater only represent a small fraction of total PCBs; in fact their hydrophobic character determines their rapid association to suspended particulate matter and sediments.…”

The study of marine pollution has been traditionally addressed to persistent chemicals, generally known as priority pollutants; a current trend in environmental analysis is a shift toward "emerging pollutants," defined as newly identified or previously unrecognized contaminants. The present review is focused on the peculiar contribution of mass spectrometry (MS) to the study of pollutants in the seawater compartment. The work is organized in five paragraphs where the most relevant groups of pollutants, both "classical" and "emerging," are presented and discussed, highlighting the relative data obtained by the means of different MS techniques. The hyphenation of MS and separative techniques, together with the development of different ion sources, makes MS and tandem MS the analytical tool of choice for the determination of trace organic contaminants in seawater. © 2016 Wiley Periodicals, Inc.

“…The pharmaceutical industry is particularly interested in using rapid and efficient procedures for qualitative and quantitative analysis to cope with a large number of samples and reduce the time required for delivery of results. The application of novel approaches in HPLC such as suitable stationary phases or high‐resolution chromatographic systems utilizing smaller particles in routine practice might be of economic interest , because of their potential to induce a simultaneous improvement in efficiency, optimal velocity and mass transfer, albeit the cost of pressure .…”

The chromatographic separation of traditional Chinese medicines is still a highly challenging task in analytical science with respect to its hundreds and thousands of chemical compounds, while increase of separation efficiency can greatly improve the separation power of chromatographic column for traditional Chinese medicine. In this study, 13 bioactive components in HuanglianShangqing pill were selected as an index to optimize the separation conditions and evaluate the system suitability of three commercially available columns packed with 1.8, 3.5, and 5.0 μm particles. The chromatographic separations were obtained by the most appropriate Eclipse Plus C18 column (100 × 2.1 mm, 3.5 μm) within 45 min using gradient elution with aqueous-ammonium acetate (10 mmol/L, pH 5.0) and acetonitrile, at a flow rate of 0.3 mL/min and an operating temperature of 30°C. The quality of HuanglianShangqing pill was assessed through combining simultaneous quantification of 13 compounds with fingerprint analysis. For the qualitative analysis, mass spectrometry was used to confirm the 13 compounds. All the validation data conformed to the acceptable requirements. For the fingerprint analysis, 32 peaks were selected as the common peaks at 254 nm to evaluate the similarities among HuanglianShangqing pills obtained from ten manufacturers.
