(2007-09-27)In this work, the possibility of performing 3D multielemental chemical maps of non-flat samples by laser-induced breakdown spectroscopy (LIBS) is demonstrated for the first time. In a first step, information of surface ...
-
(2007-09-27)A novel experimental technique, 3D micro-particle-induced X-ray emission (PIXE) is described in the present paper. 3D Micro-PIXE is realized by using an X-ray optic in front of the detector, thus creating a confocal ...
-
(2007-02-28)Powdered samples have been pressed, utilising a standard KBr infrared (IR) press, to produce mechanically stable 13 mm discs. Three absorbing, organic based binders have been employed in this work, vanillic acid, pyrazinoic ...
-
(1991)The accuracy of inductively coupled plasma mass spectrometry (ICP-MS) for the multi-element analysis of human tissue has been assessed by analysis of National Institute of Standards and Technology (NIST) Standard Reference ...
-
(1996)A simple method for measuring trace levels (g g1) of Pb in bone by electrothermal atomic absorption spectrometry (ETAAS) is described. ETAAS instrumentation equipped with a transverse Zeeman-effect background correction ...
-
(200710-24)Accurate determination methods for 234U/238U and 230Th/232Th using multiple collector (MC) ICP-MS with a single secondary electron multiplier through a retarding potential quadrupole filter (RPQ-SEM) have been developed. ...
-
(2007-02-28)A method for accurate selenium determination in blood serum by isotope dilution analysis (IDA) was developed. Selenium was determined by ICP octopole reaction system MS using xenon as the collision gas (130160 L min1) in ...
-
(2007-07-24)In this work, we describe a procedure for the structure elucidation of selenium compounds, based on accurate mass analysis of ions by means of liquid chromatography electrospray time-of-flight mass spectrometry LCTOFMS. ...
-
(1986)A comparison of the analytical performance of five cloud chambers of different geometry used in conjunction with a commercial concentric glass nebuliser is reported. The comparison was based on measurements of transport ...
-
(1986)A comparison of six commercially available curve fitting algorithms for calibration in flame atomic absorption spectrometry (FAAS) has been made. Programs using the algorithms were written in BASIC for a microcomputer and, ...
-
(1986)The analytical performance of two sample introduction-torch configurations for inductively coupled plasma atomic emission spectrometry has been optimised using the variable step-size simplex method and signal to background ...
-
(2001Unassi)Urinary arsenic speciation provides information on recent arsenic exposure. The literature reported analysis of NIST SRM 2670 Freeze-dried Urine indicates considerable discrepancy in species specific concentration. In this ...
-
(1992)Addition of 1% N2 to the coolant Ar gas flow at a nebulizer gas flow rate of 0.95 dm3 min1 can eliminate 40Ar35Cl+ and dramatically reduce 35Cl16O+ and 37Cl16O+, without losing sensitivity for a representative analyte, In. ...
-
(1996)A semiquantitative inductively coupled plasma mass spectrometric (ICP-MS) analysis protocol for biological materials was developed to include water-soluble tertiary amines with microwave heated sample preparation. Certified ...
-
(200110-15)The already established technique of pulsed glow discharge spectroscopy is extended in these studies to the application of a second pulse applied at a variable delay after a first pulse. The net discharge then consists of ...
