“…Dispersive liquid-liquid microextraction (DLLME) is an e cient and fast liquid-phase microextraction method proposed by Rezaee (Rezaee, et al, 2006) in 2006. The main improvement work is concentrated on innovating the dispersion method (Psillakis, 2019;Saleh, et al, 2009;Zhong, et al, 2019), updating the phase separation method (Guo, et al, 2016;Ngaosi, et al, 2016;Rezaee, et al, 2012;Ye, et al, 2016;Zhong, et al, 2019), and the usage of low-toxic extractants as much as possible. The ionic liquid (Marcinkowska, et al, 2019) which was used to replace the toxic extractant in DLLME (Montalbán, et al, 2018;Wu, et al, 2013) was found to be harmful to environment recently (Montalbán, et al, 2018).…”

With the development of research, it was found that the dispersive liquid-liquid microextraction (DLLME) was limited by the tedious extraction process and toxic extractant. A thermo-switchable deep eutectic solvent (DES) was applied to the DLLME as a green extractant in this paper. The DES can be dispersed and aggregated by shaking and heating in the water during the extraction process due to the surfactant and thermo-switchable properties, which shortened the extraction time as low as 5 minutes. The feasibility of the developed method was verified using 4 organophosphorus pesticides and 5 pyrethroids as targets in simulated water samples, which showed good precision (RSD%, 0.8-9.7, n=3) and low detection limit (0.16-0.81 µg L−1, S/N = 3) under the optimal extraction conditions. This method was used to detect the pesticide content in four natural rivers in Xi'an, and the recoveries of these spiked samples at three concentrations levels were among 81–113%. This is the first time to combine the toxic-free and thermo-switchable properties of DES in DLLME to proposes a simple, fast, effective, and green pretreatment method.

A simple and highly sensitive method is developed for the simultaneous determination of Ni2+, Cr2O72−, Co2+, and Hg2+ by using in syringe low density solvent-dispersive liquid liquid microextraction (ISLD-DLLME), followed by high performance liquid chromatography with a UV detector. The four metal ions were derivatized with pyrrolidine dithiocarbamate (PDC) based on complexation before their enrichment by ISLD-DLLME in which 1-octanol and methanol were used as the extraction solvent and the dispersive solvent, respectively. The extraction was performed in a commercially available syringe under vortex agitation. Phase separation was achieved without centrifugation, and the extraction phase was easily collected by moving the syringe plunger. Parameters affecting the extraction efficiency were studied and optimized. Under the optimum conditions, the four metal-PDC complexes were detected within 18 min, and ISLD-DLLME could increase the detection sensitivity in the range of 64–230 times compared to the direct HPLC analysis. The obtained limits of detection (LODs) were found to be in the range of 0.011–2.0 µg L−1. The applicability of the method is demonstrated for freshwater fish, shrimp, and shellfish samples. In addition, the results are in good agreement with those obtained by inductively-coupled plasma-optical emission spectrometry (ICP-OES).

“…Recently, our lab has reported a fully automated method for the identification of phosphopeptides from cell lysate using INtip technology [14]. Much of the previous work with dSPE tips employed organic solvents to aid subsequent separations [15,16]. None of these studies, however, has demonstrated the use of dSPE for biomacromolecule purification from cell lysates.…”

Automation gives researchers the ability to process and screen orders of magnitude higher numbers of samples than manual experimentation. Current biomacromolecule separation methodologies suffer from necessary manual intervention, making their translation to high-throughput automation difficult. Herein, we present the first characterization of biomacromolecule affinity purification via dispersive solid-phase extraction in a pipette tip (INtip). We use commercially available resin and compare efficiency with batch and spin column methodologies. Moreover, we measure the kinetics of binding and evaluate resin binding capacities. INtip technology is effective on, and scalable for, an automated platform (INTEGRA ASSIST). The results suggest that high-throughput biomolecular workflows will benefit from the integration of INtip separations.
