Introduction: MIL 03346 is a nakhlite which has been recently recovered from Miller Range in Antarctica [1]. The Meteorite Working Group (MWG) allocated us a 0.5 g rock chip for a chemical study. We have determined the concentrations of 45 elements using a combination of ICP-AES (inductively coupled plasma-atomic emission spectrometry) and ICP-MS (inductively coupled plasma-mass spectrometry) p...

background and purpose: determination of heavy metals in oils is necessary to establish quality standards on a country level. this study aimed to determine of heavy metal contents (cr, ni, as, cd, hg, pb, sb, sn, sr, al) in 12 seed oil samples in iran by inductively coupled plasma-optical emission spectrometry (icp-oes). materials and methods: the concentrations of heavy metal were determined b...

background : road runoff is a linear diffuse source of pollution, with very specific pollutant characteristics and ability to discharge into the environment. heavy metal pollution in road runoff has caused widespread concern since the last century. therefore, the purpose of this study was to assess fe, pb, and cd concentrations in surface runoff from regions with high traffic intensity in the c...

A low flow, parallel path Mira Mist CE nebulizer designed for capillary electrophoresis (CE) was evaluated as a function of make-up solution flow rate, composition, and concentration, as well as the nebulizer gas flow rate. This research was conducted in support of a project related to the separation and quantification of cobalamin (vitamin B-12) species using microseparation techniques combine...

BACKGROUND Boron neutron-capture therapy (BNCT) is a drug-targeted binary radiotherapy for cancer. The (10)B capture of thermal neutrons induces secondary radiation within cells during irradiation. The most widely used boron carrier is 4-dihydroxyborylphenylalanine (BPA). The duration and timing of the irradiation is adjusted by monitoring (10)B concentrations in whole blood. METHODS We devel...

Phosphorus (P) can limit crop production in many soils, and soil testing is used to guide fertilizer recommendations. The Mehlich III (M3) soil test is widely used in North America, followed by colorimetric analysis for P, or by inductively coupled plasma-based spectrometry (ICP) for P and cations. However, differences have been observed in M3 P concentrations measured by these methods. Using 3...

Introduction: This study was carried out to determine elements (Li, Na, K, Mg, Ca, Ba, B, Al, Si, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Ag and P) in the Suaeda vermiculata (S. vermiculata) and Suaeda aegyptiaca (S. aegyptiaca) in three different regions of Southern Iran using inductively coupled plasma optical emission spectrometry (ICP-OES) after microwave-assisted acid digestion. Materials and ...

UNLABELLED Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disease, characterized by maternal pruritus and raised serum bile acids. Our objectives were to describe the epidemiology and pregnancy complications associated with severe ICP and to test the hypothesis that adverse perinatal outcomes are increased in these women. A prospective population-based case-control st...

The inorganic elements potentially migrating from cork to a food simulant [a hydroalcoholic solution containing 12 and 20% (v/v) ethanol] have been determined by means of inductively coupled plasma (ICP) with atomic emission and mass spectrometric detection. The experimental instrumental conditions were evaluated in depth, taking into account spectroscopic and nonspectroscopic interference caus...

The source of signal variations that governs the analytical performance of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was investigated in this study. In order to specify the source of signal variations of LA-ICP-MS, laser-induced plasma (LIP) Fe emission, LA-ICP-MS Fe+ and LA-ICP-MS Ni+ signals were used as internal standards for the determination of trace elements ...
