This article will briefly describe these three techniques, and point out the important criteria by which to judge their applicability to your own analytical problems. Table 1 below shows a checklist of common analytical requirements and may help in the assessment of the techniques. For many people with an ICP-OES background, ICP-MS is a plasma with a mass spectrometer as a detector. Mass spectr...

Metals in particulate matter (PM) are considered a driving factor for many pathologies. Despite the hazards associated with particulate metals, personal exposures for at-risk workers are rarely assessed due to the cost and effort associated with monitoring. As a result, routine exposure assessments are performed for only a small fraction of the exposed workforce. The objective of this research ...

The aim of the study was to compare concentrations risk elements (As, Cu, Mn, Ni, Pb, Zn) in alluvial soil, which were measured by a portable X-ray fluorescence analyser (pXRF) situ (FIELD) and laboratory (LABORATORY). Subsequently, regression equations developed for individual through method construction model, results pXRF with classical analysis (ICP-OES). accuracy measurement, expressed coe...

The aim of the study was to compare the two reference methods for the determination of boron in water samples and further assess the impact of the method of preparation of samples for analysis on the results obtained. Samples were collected during different desalination processes, ultrafiltration and the double reverse osmosis system, connected in series. From each point, samples were prepared ...

In the present paper, the elemental composition of wood ashes obtained by the combustion of wood in a fireplace was determined with the use of ICP-MS and ICP-OES techniques. Wood ashes may find a potential application as deacidifying agents and soil conditioners, since they contain calcium (in the form of CaCO(3) and CaO), potassium (in the form of K(2)SO(4) and K(2)CO(3)) and significant level...

We have determined and compared trace metals concentration in saliva taken from chemical warfare injures who were under the exposure of mustard gas and healthy subjects by means of inductively coupled plasma optical emission spectroscopy (ICP-OES) for the first time. The influence of preliminary operations on the accuracy of ICP-OES analysis, blood contamination, the number of restored teeth in...

Analysis of gunshot residue (GSR) is a crucial evidences for a forensic analyst in the fastest way. GSR analysis insists a suitable method provides a relatively simple, rapid and precise information on the spot at the crime scene. Therefore, the analysis of Cu(II) in GSR using cyclic voltammetry (CV) on screen printed carbon electrode (SPCE) is a better choice compared to previous alternative m...

Determination of potential contaminants elements in food packing films arising from contact with acidic aqueous foods was undertaken by inductively coupled plasma optical emission spectrometry (ICP OES) in accordance with DIN EN 1186-1. Test sections from plastic films were totally immersed in 3% w/v CH3COOH used as the food simulant. Testing was conducted under three conditions: (1) 10 days at...

This paper presents a case of poisoning of a male whose death occurred about 3 hours after onset of pain in his abdomen. The autopsy revealed semi-liquid contents in the stomach “with a distinct odour of carbide”. Post-mortem material together with a public prosecutor’s decision (request) for an expert opinion on the presence of carbide (calcium carbide, CaC2) or any other poisons in the stomac...

The concentrations of zinc (Zn), iron (Fe) and copper (Cu) in both human milk and infant formula were determined using a new sample preparation method, by inductively coupled plasma - optical emission spectometry (ICP-OES) and flame atomic absorption spectrometry (FAAS). Human milk samples were diluted in ultrapure water. The infant formula of powder samples (suitable for an infant 1-6 months o...
