Role of Sample Decomposition and Preconcentration in Elemental Trace Analysis
Progress in elemental trace analysis means that lower con— centrations can be determined in a more reliable and efficient way. The demands posed to trace element analysis follow generally the tendency that lower and lower concentrations should be determined in matrices which become more and more complex. The most economical scientific strategy depends strongly on the element to be determined, o...

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولMicrowave acid sample decomposition for elemental analysis
resistant version of the standard Zymark arm was chosen for this project. A special problem was posed, however, in the handling of these solutions in the volumes required (10-300 mL) without contaminating the delivery devices. A solution was found through the use of peristaltic pumps and three-way pinch valves. These components were assembled into a pump station controlled by digital signals fr...
متن کاملPreconcentration in Inorganic Trace Analysis
Preconcentration in trace analysis lowers the detection limit, simplifies the treatment of a representatIve sample, facilitates calibration, reduces the need for various standard reference samples and frequently involves separation of the matrix in analysis of toxic, radioactive and expensive materials. In this paper, the types of preconcentration are considered and quantitative characteristics...
