Continuum source atomic absorption spectrometry in a graphite furnace with photodiode array detection

Abstract: A graphite furnace continuum source atomic absorption spectrometer using a photodiode array detector is described that provides high-resolution wavelength versus absorbance spectra over a 2.5-nm range for a single atomization step. The multiwavelength detection power allows the simultaneous determination of several elements, reduces problems caused by spectral interferences, and automatically corrects for nonzero background absorbance. Each spectrum is acquired in 0.33 s, and several successive spectra can be … Show more

“…The only other 'simultaneous' CS AAS instruments described in the literature for ET AAS used photodiode array detectors that covered a spectral range of 2.5 nm [48], 10 nm [49] and 4 nm [50], respectively, and only elements that had absorption lines falling within this narrow spectral window could be detected simultaneously. In their first work the authors investigated a 19-component mixture as well as a standard bronze and a seawater sample [48] without carrying out real determinations.…”

“…The most spread variant of the ICLS with a broadband tunable laser is similar to that employed in conventional continuum source AAS [4], but the latter has smaller limits of detection. Therefore the ICLS commonly used the same vaporizers as the AAS: often -flame atomization [5,6], rarely -electrothermal vaporization [7,8], and in single works -electrical discharge [9,10] and laser ablation [11,12] V.S.…”
