Analyse de l'Etain par Spectrophotometrie d'absortion atomique avec four ectrothermique. Application aux organismes marins ArchiMer
Thibaud, Yves.
The author presents an analysis technique permitting the determination of the tin in the tissues of marine organisms. This technique is only the application of the spectrophotometry of atomic absorption with atomization in the electrothermic oven. After the acid attack of the sample, the solution is put in a graphite oven to atomize the tin selectively and quantitatively. The detection limit obtained, 0,5 mu g/g of the lyophilized flesh is very satisfactory, to show the purport variations in shells from different origins.

Determinación experimental del límite de detección, en el análisis de metales pesados en organismos marinos, por espectrofotometría de absorción atómica OceanDocs
Moreno, V.J.; Pérez, A..
The determination limit is defined as the minimum concentration of a substance in a sample that can be distinguished from the background with a given probability, using a particular analytical method. It is assumed that the concept of detention can be used satisfactorily to quality an analytical method. Some criteria which are necessary for intercalibration purpose are given in this paper. An algebraic method to calculate the detection limit easily and with minimum experimental work was developed. A method to determine the number of repetitions needed when the levels of the analyzed substance are near or under the detection limit of the method is also shown.
