Abstract
A single computer program, for use in especially highly precise and accurate applications of the Walsh atomic absorption method, is designed to allow an analyst the freedoms (1) to determine the concentrations of up to 11 elements in an unrestricted number of samples; (2) to use up to 40 differently named standards and/or series of standards simultaneously, with or without a dilution option; (3) to fit any standard curve and associate it with either one equation or two; (4) to make the equation of all or part of any standard curve a polynomial of either first or second degree; and (5) to have standard curve equation coefficients and/or coordinates of certain points on the standard curve printed out in easily readable form. The concentration of a given element of interest, in any sample, is treated as a variable with random properties. Up to 26 estimates of this concentration can be made, and, from them, the program computes the mean, standard deviation, coefficient of variation, and both 95 and 99% confidence limits about the mean.
