Environmental applications of capillary gas chromatography coupled with atomic emission detection — a review

Abstract

SummaryEnvironmental applications of capillary gas chromatography coupled with atomic emission detection (GC-AED) have been reviewed with emphasis on both the commercial and laboratory-built systems. Attention was focused on 1) element-selective detection of non-metallic as well as metallic pollutants, 2) identification of contaminants, and 3) sample preparation considerations.

Some unique properties of gas chromatography coupled with atomic-emission detection

“…A representative selection of applications of the AED to real-world problems is listed in Table 2; this should be consulted for experimental details. Rather than give an overview of topics covered in earlier reviews [2,36,37,38,39], e.g. limits of detection, linearity range, selectivity relative to carbon, etc., other properties of the AED will be discussed in some detail in this review -the possibility of a compound-independent calibration, calculation of element ratios in an unknown compound, derivatization of compounds for better detection by AED, and analysis of isotopes of several elements.…”

“…Nearly all the properties reported for the AED and applications cited in this review have been obtained on one of those instruments. Information on other types of microwave-induced plasma in gas chromatography is available elsewhere [1,2].Several properties contribute to the unique standing of the AED; some of these will be discussed in this paper. The detector can be considered as a simultaneous multielement-selective and universal detector, because all the elements of the periodic system can, in principle, be detected (with the exception of helium, which is used as the plasma gas).…”

Data correlation in on-line solid-phase extraction-gas chromatography-atomic emission/mass spectrometric detection of unknown microcontaminants

“…This helps to explain the growing popularity of the atomic emission detector (AED) [1,2,3]. An additional advantage of this detector is that the response per mass unit of an element is more or less independent of the structure of the analyte of interest [4,5,6,7], although this statement is not uncontested [8,9].…”

Drug Monitoring in Human Plasma by Capillary Gas Chromatography Coupled with Atomic Emission Detection. Potential and Limitations

“…While GC-AED has been utilized within several application fields to analyze environmental samples [1], petroleum products [2], polymers [3], food [4], chemical warfare agents [5], and essential oils [6], very little information has been reported on the applicability of the technique for drug analysis. GC-AED has been utilized for the determination of triclosan in human dental plaque [7], to study 13 C labeled metabolites of caffeine in human urine [8,9], for quantitative determination of propofol in rat liver microsomes [10], and for the quality control of selenium containing amino acids in pharmaceutical formulations [11].…”
