Solventless microextraction techniques for water analysis [PDF]
TrAC Trends in Analytical Chemistry, 2019 Abstract Microextraction techniques have been proven to provide similar or better results in terms of sensitivity and reproducibility in comparison to liquid-liquid extraction (LLE) and solid-phase extraction (SPE). Furthermore, the high time efficiency and decreased workload leads to a higher sample throughput. In this review the state of the art of
