-
(1995)A comparative study is described between the direct determination of copper species obtained by electrothermal atomization atomic absorption spectrometry (ETAAS) and the predicted data using the NSPEC computer speciation ...
-
(1995)The performance of an all solid-state Refex electrode has been evaluated as a reference electrode for pH measurement for use with a glass pH electrode, an ISFET pH probe and six encapsulated ISFET chips. It was found that ...
-
(1995)A new specific method for the kinetic analysis of 2,4-dinitrophenylhydrazine in its reaction with aliphatic amines followed by alkali hydroxide in dimethyl sulfoxide is described. This method is superior to other colorimetric ...
-
(1995)Flow injection analysis with potentiometric ion selective electrode detection is discussed in the context of sodium analysis in blood samples. A novel ionophore is used, which shows excellent selectivity for sodium over ...
-
(1995)The coupling of the HPLC and ICP techniques allows the determination of both classes of GdIII complexes, with and without the chromophoric group. The ICP signal enables the determination of the compounds containing Gd, ...
-
(1995)The pharmaceutical analyst is primarily involved in drug stability studies as he or she must develop a suitable method that will quantitate the drug in the presence of degradation products, impurities and excipients. This ...
-
(1995)The preconcentration of trace metals is often necessary for their determination in natural waters. Solid phase techniques are now widely used for this purpose, either in an off-line batch mode or, increasingly commonly, ...
-
(1995)The physico-chemical forms of phosphorus in natural waters are described and their significance in relation to biogeochemical processes discussed. Analytical techniques for the determination of orthophosphate and total ...
-
(1995)Some confusion exists in the literature on the optimization of kineticcatalytic methods of determination. Different ways of optimization are applied by the authors of papers in this field. One of the most usual ways is to ...
-
(1995)A chelating ion exchange resin membrane incorporating salicylaldoximeformaldehyde exhibits excellent selectivity for zinc ions with a concentration range from 3.0 106 to 1.0 101 mol dm3(0.206500 ppm). The sensor can also ...
-
(1995)A capillary supercritical fluid chromatograph interfaced to an unmodified benchtop quadrupole mass spectrometer has enabled the relative molecular mass determination of midecamycin A1 in positive ion chemical ionization mode.
-
(1995)A simple and rapid ELISA with a fluorescent end-point has been developed for the measurement of the cephalosporin antibiotic, ceftazidime. The ELISA can be applied to the analysis of the drug in solutions that have been ...
-
(1995)In analytical chemistry, multi-layer feed-forward (MLF) neural networks are increasingly used as a technique to model (univariate) non-linear relationships. This paper investigates the influence of the MLF network parameters ...
-
(1995)A PVC-based membrane of dibenzo-24-crown-8 exhibits good response for Cs+ in a wide concentration range (3.5 1051.0 101 mol dm3) with a near-Nernstian slope of 50.7 mV per decade of concentration of CsCl. The response ...
-
(1995)A capillary zone electrophoresis (CZE) method for the determination of sulfate in concrete digested with concentrated nitric acid is described. An electrolyte containing 50 mmol l1 thiocyanate, 10 mmol l1 tris(hydroxymet ...
-
(1995)Sulfonamides that form stable metal complexes can be accumulated at a hanging mercury drop electrode in the presence of copper(II). In this preliminary study sulfadimidine, sulfathiazole, sulfamerazine, sulfadiazine and ...
-
(1995)Maintaining samples of four moorland soils of low base status from a podzol profile in a field-moist state prior to analysis is shown to result in significant changes in exchangeable cation concentrations, cation exchange ...
