Abstract
A more powerful light source, a high-resolution monochromator and a longer 2048-photodiode array combine to boost the capability of continuum source atomic absorption spectrometry. The technique allows detection of as many as 11 elements within the 9-nm spectral window, using a 5-s integration time. The higher optical throughput brings down the detection limit to as low as 0.3 ng/mL for Mg, 0.9 ng/mL for Cu and 2 ng/mL for Cd, Mn and Ag. The linear dynamic range may be expanded from three to six orders of magnitude by means of multiline monitoring for each element.
