In the present work, a simple and rapid method, namely magnetic dispersive micro-solid phase extraction (MD-μ-SPE), was developed using magnetic Fe3O4@SiO2@Ti-MOF (metal–organic framework)-nanocomposites (NCs) as a viable and efficient sorbent to pre-concentrate and assess caffeic acid (CA) in the medical ex Author information: (1)School of Chemical Sciences, Universiti Sains … [17] firstly reported this approach in which multiwalled carbon nanotube (MWCNTs) was used to extract or- ganophosphorus pesticides (OPPs) from environmental samples. Several main parameters, including the amount of the sorbent, extraction time, ionic strength and desorption conditions, were independently optimized and the results were compared to find the best extraction setup for dispersive micro-solid phase extraction.

Solid-phase microextraction (SPME) is a simple, sensitive, rapid and solvent-free technique for the extraction of analytes from gaseous, liquid and solid samples and takes a leading position among microextraction methods. human urine using micro-elution solid phase extraction Key words SPE, SOLA, SOLAμ, SCX, Hypersil GOLD aQ, opiates Goal To describe a reproducible optimization procedure for the isolation of opioids from human urine utilizing solid phase extraction (SPE). Solid-phase microextraction (SPME) is a simple, sensitive, rapid and solvent-free technique for the extraction of analytes from gaseous, liquid and solid samples and takes a leading position among microextraction methods. We know perfectly well that a cleaner sample yields better result. Solid Phase Micro Extraction is to be used as the main extraction technique and detection using several gas chromatography. The area of study will cover part of Peninsular Malaysia.
