Inner diameters of the torch and the sample injector tube are 10 mm and 1.5 mm, respectively.

A relative standard deviation (RSD) of 4.3 - 8.5% for ETV was obtained, while 2.15 - 6.84% RSD was found for DMD.

Journal: Analytical Sciences Volume: 21 - Pages: 569-71 DOI: 10.2116/analsci.21.569 Products: µflow PFA-100 nebulizer Abstract: A low-pressure inductively coupled plasma atomic emission system with a double membrane desolvator (DMD) was built in the laboratory.

The analytical performance of the ETV was tested and compared with that of a PFA pneumatic nebulizer with a double membrane desolvator (DMD).

The limits of detection of the ETV were obtained in the range of 3.4 ng to 758 ng for Zn, Cu, Co, Fe, and Mg, while those of the PFA nebulizer were in the range of 53 ppb to 286 ppb.

The migration/elution order of the deoxynucleotides investigated was obtained by comparison with the migration/retention times of commercially available d NMP's.

Furthermore it was checked if HPLC-ESI-MS can be operated under the same chromatographic conditions for the confirmation of the elution order and for the characterisation of unknown peaks.The fulvic acids reduced the cadmium toxicity by about the same amount as humic acids, from 4.4 to 18.6 µmol/L, but they had no effect on copper toxicity.Analysing the chemical speciation of cadmium and copper in the presence of humic components and under toxicity test conditions we can say that the appreciable decrease of EC is not related to changes in their speciation; we can hypothesize that this is due to different processes, as well as to blocking of the lysosomal membrane.The molecular nitrogen ion consistently obtained the same temperatures as those of the high rotational temperatures of the OH radical.This result suggests that the high density of rotational states of these molecules, N produced a decrease of excitation temperatures of Fe II from 10400 to 9200 K.Measurements of the complexing capacity of solutions containing these organic ligands were carried out by a titration procedure followed by DPASV and toxicity tests were carried out using lysosomes isolated from rat liver.
