Atomic emission spectroscopic detection AESD in chromatography

ATOMIC EMISSION SPECTROSCOPIC DETECTION (AESD) IN CHROMATOGRAPHY [Pg.3]

Four modes of atomic spectroscopy have been interfaced for chromatographic detection, fiame emission (FES), atomic absorption (AAS), atomic fluorescence (AFS), and atomic plasma emission (APES) [2-3]. In contrast to AAS, APES can accomplish simultaneous multielement determination, while giving a good dynamic measurement range and high sensitivities and selectivities over background elements in many cases. [Pg.3]

The development of many alternative plasma sources has led to a resurgence of analytical atomic emission spectroscopy in recent years. The major plasma emission sources used for gas chromatographic detection have been the microwave-induced helium plasma, under atmospheric or reduced pressure (MIP), and the DC argon plasma (DCP). The inductively coupled argon plasma (ICP) has been used much less for GC than as an HPLC detector [4]. [Pg.3]
