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.
