Automated Atomic Spectrometric Analysis

Characterization of a computerized photodiode array spectrometer for gas chromatography-atomic emission spectrometry

“…Instruments with fixed optics, such as direct readers, sometimes use the detector outputs from other channels for background correction (11,12). In gas chromatographic applications, a version of this method is to subtract a calibrated amount of the signal on a carbon channel from the signal on a heteroatom channel (13).…”

“…Thus, most current methods for seawater analysis employ some kind of analyte preconcentratioin along with matrix rejection techniques. These preconcentration techniques include coprecipitation (1, 2), solvent extraction (3)(4)(5), column adsorption (4)(5)(6), electrodeposition (7-10), and Donnan dialysis (11,12).…”

“…Measurement techniques that can be employed for the determination of trace metals include atomic absorption spectrometry [AAS] (5,7,8), anodic stripping voltammetry (11,13,14), differential pulse cathodic stripping voltammetry (15,16), inductively coupled plasma atomic emission spectrometry [ICP-AES] (9,12,17), and liquid chromatography of the metal chelates with ultraviolet-visible absorption 0003-2700/90/0362-1043S02.50/0 © 1990 American Chemical Society…”
