Characterisation of airborne particulates and associated trace metals deposited on tree bark by ICP-OES, ICP-MS, SEM-EDX and laser ablation ICP-MS
Particulate matter accumulated on tree bark specimens was examined in order to investigate its potential use as a natural monitor to study the impact on local atmospheric conditions. Tree bark from sargent cherry (Prunus sargentii) and sugar maple (Acer saccharum Marsh) trees was collected from four locations: Drax (North Yorkshire), Darley Dale (Derbyshire), Galway (Ireland) and Tristan da Cun...
متن کاملICP-OES, ICP-MS and AAS Techniques Compared
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...
متن کاملSimultaneous separation and determination of Tl(I) and Tl(III) by IC-ICP-OES and IC-ICP-MS
A new hyphenated method was developed for the speciation of Tl. In this method, Tl(III) was complexed with DTPA to form a Tl(III)-DTPA anionic complex. Tl(I) did not form a complex with DTPA. The two species were separated simultaneously by means of ion chromatography using a Dionex cation exchange guard column, CG12A, and 15 mmol/l nitric acid as eluant. When ICP-OES was used as detector the d...
متن کاملDetermination of trace impurities in germanium dioxide by ICP-OES, ICP-MS and ETAAS after matrix volatilization: a long-run performance of the method.
High-purity germanium compounds (e.g. germanium dioxide) are used these days in several applications (e.g. germanium-based detectors, semiconductors, fiber-optic systems). Thus, reliable methods for the routine determination of trace element impurities from germanium compounds must be developed. In this study, inductively coupled plasma mass spectrometry, inductively coupled plasma optical emis...
متن کاملDetermination of Trace Metals in Human Urine Using the NexION 300/350 ICP-MS
The monitoring of trace metals in human urine plays an important role in research. Traditionally, urine analysis has been accomplished by graphite furnace atomic absorption (GFAA). However, when large numbers of samples are analyzed for multiple elements, GFAA becomes very cumbersome and restrictive, since it can only determine one element at a time. Additionally, the detection capability of IC...
