Publication Metadata only Multiple stirred-flow chamber assembly for simultaneous automatic fractionation of trace elements in fly ash samples using a multisyringe-based flow system(2008-10-01) Warunya Boonjob; Manuel Miró; Víctor Cerdà; Mahidol University; Universitat de les Illes BalearsThere is a current trend in automation of leaching tests for trace elements in solid matrixes by use of flow injection based column approaches. However, as a result of the downscaled dimensions of the analytical manifold and execution of a single... extraction at a time, miniaturized flow-through column approaches have merely found applications for periodic investigations of trace element mobility in highly homogeneous environmental solids. A novel flow-based configuration capitalized on stirred-flowPublication Metadata only Determination of trace elements in herbal tea products and their infusions consumed in Thailand(2006-09-06) Sumontha Nookabkaew; Nuchanart Rangkadilok; Jutamaad Satayavivad; Chulabhorn Research Institute; Mahidol UniversityNineteen elements, Mg, Al, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Sr, Sb, Ba, As, Cd, Hg, and Pb, were determined in three types of popular herbal tea products, Gynostemma pentaphyllum, Camellia sinensis, and Morus alba. These herbal tea products..., both imported and locally made products, are widely consumed in Thailand and worldwide. Microwave-assisted acid digestion was used for all of the samples, and the element contents were determined by ICP-MS. The concentrations of all elements variedPublication Metadata only Concentrations of Trace Elements in Organic Fertilizers and Animal Manures and Feeds and Cadmium Contamination in Herbal Tea (Gynostemma pentaphyllum Makino)(2016-04-27) Sumontha Nookabkaew; Nuchanart Rangkadilok; Norratouch Prachoom; Jutamaad Satayavivad; Chulabhorn Research Institute; Chulabhorn Graduate Institute; South Carolina Commission on Higher Education; Asian Institute of Technology Thailandthe concentrations of trace elements in commercial organic fertilizers (fermented and nonfermented) composed of pig and cattle manures available in Thailand. Pig and cattle manures as well as animal feeds were also collected from either animal farms or markets... to agricultural soil could increase some potentially toxic elements in soil, which may be absorbed by plants and, thus, increase the risk of contamination in agricultural products.Item Metadata only Evaluation of magnetic hyperthermia, drug delivery and biocompatibility (bone cell adhesion and zebrafish assays) of trace element co-doped hydroxyapatite combined with Mn-Zn ferrite for bone tissue applications(2024-09-16) Tithito T.; Sillapaprayoon S.; Chantho V.; Pimtong W.; Thongbunchoo J.; Charoenphandhu N.; Krishnamra N.; Yong N.; Lert-Itthiporn A.; Maneeprakorn W.; Pon-On W.; Tithito T.; Mahidol Universityapatite based on trace element co-doped apatite (Ca10−δMδ(PO4)5.5(CO3)0.5(OH)2; M = trace elements of Mg, Fe, Zn, Mn, Cu, Ni, Mo, Sr and BO33−; THA)-integrated-biocompatible magnetic Mn-Zn ferrite ((Mn, Zn)Fe2O4 nanoparticles, BioMags) called THAiPublication Metadata only Elemental composition of Thai rice and beans by instrumental neutron activation analysis(2009-07-01) S. Laoharojanaphand; A. Busamongkol; S. Chaiyasith; V. Permnamtip; M. Parengam; S. Srianujata; Thailand Institute of Nuclear Technology; King Mongkut's Institute of Technology Ladkrabang; Mahidol UniversityThe nutrient value of Thai rice and bean in terms of minor and trace element content has been evaluated using INAA. Six varieties of rice and six of beans bought from three local markets in 2006-2007 were investigated under this study. Elemental... compositions were determined using the comparator technique. Precision, accuracy and detection limits of each element found were also calculated. Three minor (Ca, K, Mg) and eight trace elements (Al, As, Br, Cl, Cu, Fe, Mn, Zn) were determined in these ThaiItem Metadata only Stable isotope ratio analysis: an emerging tool to trace the origin of falsified medicines(2024-05-01) Roncone A.; Kelly S.D.; Giannioti Z.; Hauk C.; Caillet C.; Newton P.N.; Perez-Mon C.; Bontempo L.; Roncone A.; Mahidol Universitythese products. This review presents the main approaches, based on stable isotope ratios of the bio-elements, mainly Isotope Ratio Mass Spectrometry and Site-specific Natural Isotopic Fractionation by Nuclear Magnetic Resonance, that can contribute to identifyingPublication Metadata only Direct multi-element analysis of crude oils and gas condensates by double-focusing sector field inductively coupled plasma mass spectrometry (ICP MS)(2010-05-10) Pawel Pohl; Nopparat Vorapalawut; Brice Bouyssiere; Herve Carrier; Ryszard Lobinski; Universite de Pau et des Pays de L'Adour; Wrocław University of Science and Technology; Mahidol University; Politechnika Warszawskawere completely eliminated at a resolution of 4000 allowing the detection limits at the low pg g-1 level to be obtained (typically one order of magnitude lower than using a quadrupole ICP MS). A method for the routine comprehensive trace elementPublication Metadata only Towards chloramphenicol detection by inductively coupled plasma mass spectrometry (ICP-MS) linked immunoassay using gold nanoparticles (AuNPs) as element tags(2012-05-01) Purim Jarujamrus; Runglawan Chawengkirttikul; Juwadee Shiowatana; Atitaya Siripinyanond; Mahidol UniversityThis paper describes the feasibility for trace analysis of chloramphenicol using a novel immunoassay by coupling competitive measurement of chloramphenicol (CAP) to ICP-MS by the use of CAP labeled with AuNPs. Polyclonal rabbit anti-mousePublication Metadata only Bioimaging of copper deposition in Wilson's diseases mouse liver by laser ablation inductively coupled plasma mass spectrometry imaging (LA-ICP-MSI)(2013-08-01) M.
