A continuous-dilution calibration technique for flame atomic-absorption spectrophotometry.
Calibration in atomic-absorption spectrometry is achieved by means of a concentrationgradient chamber using a single concentrated standard solution. Calibration is rapid and extends over the entire working concentration range of the analyte, irrespective of the shape of the conventionally obtained calibration curve. No curve-fitting approximations are involved. With well-designed apparatus, deviations are less than 1%.
