Environmentally friendly sample treatment for speciation analysis by hyphenated techniques

Green Analytical Chemistry: Application and Education

“…Modern analytical chemists have developed a variety of tools that minimize pretreatment wastes though few of these are discussed in modern instrumental analysis texts. Among the most common and technologically simple innovations are solid sorbants (8). These materials address the thorny challenge and solvent intensive nature of organic extraction from aqueous solutions.…”

“…These adaptations reduce the overall solvent use and speed the extractions. These methods include accelerated solvent extraction (ASE) (14) and supercritical fluid extraction (SFE) (8).…”

Greening Sampling Techniques

“…The main advantages of SFE are high preconcentration rates, cleanliness and safety, quantitative capability, possibility for in-field sampling, on-line coupling with hyphenated techniques and automation [33].

Atomic spectrometry update. Advances in atomic emission, absorption and fluorescence spectrometry and related techniques

“…A paper entitled ''Environmentally friendly sample treatment for speciation analysis by hyphenated techniques'' has also been published. 519 This too discussed modern preparation techniques and highlighted their improved efficiency, the reduced time and volume of solvent required and raised the possibilities of miniaturisation and automation. An overview of As speciation in biological tissues has been presented by McSheehy et al, in which the role of speciation analysis in understanding the environmental cycle and the preparation of CRMs for quality control were discussed.…”
