A hydride generation nitrogen microwave induced plasma optical emission spectrometry (HG-MIP OES) system was developed for lead determination.

acacia nilotica (thorn mimosa) is used locally for various medicinal purposes by traditionalists and herbalists in northeastern nigeria. plants products have been used since ancient times in the management of various conditions. the bark of a. nilotica has been reported to be used traditionally to manage diabetes, dysentery, leprosy, ulcers, cancers, tumor of the eye, ear and testicles, indurat...

An imaging spectrograph equipped with a CCD detector was employed to measure two-dimensional emission images from a glow discharge plasma in atomic emission spectrometry. The emission images at Zn I 334.50 nm for a zinc sample and at Cu I 324.75 nm for a copper sample could be obtained. Their emission intensities were not uniform in the radial direction of the plasma region but became weaker at...

in previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. the aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. separation was achieved on a zorbax...

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...

In this review, a full discussion and update of the state-of-the-art of gas chromatography (GC) coupled to all known plasma spectrometers is presented. A brief introductive discussion of the advantages and disadvantages of GC–plasma interfaces, as well as types of plasmas and mass spectrometers, is given. The plasma-based techniques covered include inductively coupled plasma mass spectrometry (...
