The procedure involves initial single-phase extraction of 10 g sample with 10 mL acetonitrile, followed by liquid–liquid partitioning formed by addition of 4 g anhydrous MgSO 4 plus 1 g NaCl. Dispersive micro-solid phase extraction (D-μSPE) has gained special attention in the sample preparation process due to its simplicity, speed and efficiency. In DMSPE, the target analytes were absorbed by DES-G and then desorbed by trace eluent, next, the treated samples were quantified via ultra-high performance liquid chromatography equipped … A simple, fast, and inexpensive method for the determination of pesticide residues in fruits and vegetables is introduced. Deep eutectic solvent micro-functionalized graphene (DES-G) was synthesized and first applied as the adsorbent of dispersive micro solid-phase extraction (DMSPE) to extract five pyrethroid insecticides. Dispersive microsolid-phase extraction based on metal–organic framework has been developed and applied to the extraction of triazine and phenylurea herbicides in vegetable oils in this work. Looking for abbreviations of DSPE? Solving problems with chemistry is the core of what we do. Facile dispersive solid-phase extraction based on humic acid for the determination of aflatoxins in various edible oils P. Liu, Y. Liao, H. Zheng and Y. Tang, Anal.

INTip™ Solid Phase Extraction (SPE) INTip SPE utilizes a patented technology known as Dispersive Pipette XTRaction. Aspirate & dispense steps mix loose sorbent with sample solution. Different dispersion approaches have been used within this technique to allow a close contact between the sorbent and the donor sample solution during the entrapping step, but also between the sorbent and the solvent in the elution step. Dispersive Pipette XTRaction. Dispersive Solid Phase Extraction listed as DSPE. Dispersive solid phase extraction (d-SPE) analysis is a simple and straightforward sample preparation technique suitable for a wide variety of food and agricultural products.

One specific method which has become popular is the QuEChERS technique which was created to facilitate the rapid screening of large numbers of food and agricultural samples for pesticide residues. In this study, a simple, rapid, precise, and environmentally friendly microextraction named dispersive micro-solid phase extraction based on a graphene/polydopamine composite as a sorbent was investigated for the analysis of four pyrethroids (fenpropathrin, cyhalothrin, etofenprox and bifenthrin) in … DSPE - Dispersive Solid Phase Extraction.

This device is unique from all other SPE devices because sorbent is loosely contained within a pipette tip. Incorporates the benefits of solid phase extraction into an easy-to-use pipette tip for fast sample preparation that is easy to implement. Methods , 2020, 12 , 2308

Abstract. It is Dispersive Solid Phase Extraction. The herbicides were directly extracted with MIL-101 from diluted vegetables oils without any further cleanup.
