On-line electrothermal atomic absorption spectrometry configurations: recent developments and trends

Synthesis, characterization and application of a novel ion-imprinted polymer for selective solid phase extraction of copper(II) ions from high salt matrices prior to its determination by FAAS

“…Although ETAAS and ICP-MS possess higher sensitivity to achieve lower detection limits, they do suffer from spectral and non-spectral interferences in analysis of complex samples. Therefore, separation of an analyte from the matrix is frequently needed to alleviate the effects of interferences [3][4][5][6].…”

Development of an on-line temperature-assisted ionic liquid dispersive microextraction system for sensitive determination of vanadium in environmental and biological samples

“…With the aim of reducing the eluent volume and minimizing analyte dispersion when the eluate is delivered to the graphite furnace electrothermal atomizer, the use of air-segmentation, which consists of sandwiching the eluate by air segments and transporting it into the graphite tube, was also applied [27]. As the total eluent volume (200 L) exceeded the sample capacity of the graphite furnace, two successive 100 L-aliquots were sequentially injected into the atomizer, introducing a drying step of 10 s between each injection (Table 1), while the loop of valve V 3 was refilled for the second elution.…”

A review on sequential injection methods for water analysis

“…In some reviews [19][20][21], the focus was on the evolution of flow methodologies, in which sequential injection was mentioned as a versatile and robust flow technique to couple with devices for inline treatments. Other reviews have focused on new developments in detection systems coupled with flow techniques [22][23][24][25], namely sequential injection. Some reviews of specific detection methods such as vibrational spectroscopy [22], FTIR [23], electrothermal atomic absorption spectroscopy [24] and electronic tongues [25] emphasised the versatility of flow techniques, including sequential injection.…”
