“…However, sample dilution results in a difficulty in determining the analyte elements present at trace and ultratrace levels. 10 In order to avoid matrix effects and to eliminate interelement spectral interferences, ion chromatography (IC) 11,12 and high-performance liquid chromatography (HPLC) [13][14][15] have been used as effective techniques for sample pretreatment in ICP-MS, though they have some disadvantages, such as a long measuring time (more than 1 h per sample) and lowering the detection sensitivities. Flow-injection (FI) techniques coupled with ICP-MS have been investigated for the purpose of performing the on-line sample pretreatment of high-salt-content samples.…”

A new technique for the preconcentration of trace elements and matrix elimination with a chitosan-based chelating resin was proposed as a useful pretreatment prior to a measurement by inductively coupled plasma-mass spectrometry (ICP-MS). A small volume of the sample solution (80 µl) was discretely introduced into a nebulizer of ICP-MS using a segmented flow injection (SFI) system; a maximum of fifteen elements were simultaneously measured by a single injection. A chitosan-based chelating resin containing iminodiacetate (IDA) functional groups was used for matrix elimination and enrichment of analyte metal ions. Several metal ions, such as Al, Fe, Ni, Co, Cu, Zn, Ag, Cd, Pb and U, were quantitatively retained on the IDA chelating resin in a micro-column (resin: 1 ml) at pH 6, whereas Na, K, Mg and Ca were completely eluted from the column by washing with an ammonium acetate solution. The concentrations of 24 and 26 elements in river water certified reference materials, JAC 0031 and JAC 0032, respectively, were determined by the proposed SFI/ICP-MS system after pretreating the samples with the proposed technique, as well as without any pretreatment. The thus-obtained analytical data were evaluated by comparing them with the reference values, as well as with those obtained in other studies.

Recently, inductively coupled plasma mass spectrometry (ICP-MS) has been increasingly used for trace elements in various samples because ICP-MS generally provides much better detection limits by 2 -4 orders of magnitude for most elements.1 However, it is noted here that since matrix effects are often serious in ICP-MS, ICP-AES is still useful for the determination of major, minor and some trace elements, when the concentrations of these analyte elements are higher than 1 µg/ml in the analysis solution. In addition, ICP-AES provides better analytical precision than does ICP-MS. Thus, it is desirable to use ICP-MS and ICP-AES, depending on the concentration levels of the analyte elements as well as analytical purposes.The concentrations and distribution patterns of rare earth elements (REEs), for example in rock samples, generally provide important information about the geochemical evolution and origins of magmatic rocks. Thus, REEs in geological or geochemical samples, such as rocks, sediments and soils, have been determined by neutron activation analysis, inductively coupled plasma atomic emission spectrometry (ICP-AES), and thermal-ionization mass spectrometry. 1 The present authors previously reported on the determinations of REEs in rock samples 2,3 and rare earth ores 4 by conventional ICP-AES with pneumatic nebulization. In addition, we explored the combined LC (liquid chromatography)/ICP-AES system as the analytical method for the determination of REEs in rock samples and REE oxides, where a monochromator system for single-element detection 5,6 and a polychromator system for simultaneous multielement detection 7 were employed. In these LC/ICP-AES systems, the main purpose of using LC was to separate the coexisting diverse elements and REEs in rock and other samples so as to eliminate interelement spectral interferences.Recently, ion chromatography combined with ICP-MS was applied to the determination of REEs. 8 The present authors also reported a LC/ICP-MS system for the chromatographic determination of REEs.9 Since ICP-MS generally provides much better detection sensitivities for REEs than does ICP-AES 10,11 , the analytical results for REEs obtained by the LC/ICP-MS system appeared to be more reliable than those by the LC/ICP-AES system. 9,12 Thus, in the present experiment the determination of REEs in geological samples has been investigated in more detail by the LC/ICP-MS system. Furthermore, ICP-AES and the LC/ICP-AES system were also used for determining the matrix elements and for investigating the separation efficiencies of the matrix elements from REEs in the sample solutions.

MEDM, which is derived from Motif Editor and DisplayManager,is the primarygraphicaluser interface to the EPICScontrolsystemand has also been used for other control systems. IvlEDMhas two modes of operation,EDIT and EXECUTE. In its EDIT mode it provides the drawing tools needed to design control screensfor operatorinterfaces. In its EXECUTEmode it manages those screens to communicate with the control system. MEDM provides a set of interface objects that falls into three main categories: (1) Monitors, suchas text,meters,and plots;(2) Controllers, such as buttons,menus, and sliders; and (3) Drawing Objects,such as lines,rectangles,and images. Each of these objects has many options, allowing for the developmentof screens ranging from simple to quite sophisticated.MEDMhas been developedover the last decade,primarilyat ArgonneNationalLaboratory,and is a large,welltested,extensivelyusedprogram. It runs on most flavors of UNIX, VMS, and Windows 951981NT.It has been used to design thousandsof controlscreens,such as the one shownin Fig. 1, at the AdvancedPhoton Source and other sites around the world. This paper presentsan overviewof MEDMand its features.
