“…High specificity in the extraction step may reduce the costs and complexity of the final detection system. New SLMs have been addressed recently in several research papers, both using pure solvents [30] , [34] , [35] and solid additives in the SLM [12] , [36] , [37] , [38] . With respect to pure solvents, a range of alkylated phosphates and phosphites have been studied recently, and tributyl phosphate and bis(2-ethylhexyl) phosphite (DEHPi) were identified as new solvents providing efficient extraction of polar basic analytes [35] , [39] .…”

“…While substantial efforts have been reported on optimizing the chemical conditions in the SLM, much less research has been reported on dissolution of additives in the sample, with the purpose of improving mass transfer. However, in several recent papers, surfactants have been added to the sample to improve extraction recoveries [36] , [42] , [44] , [45] . In one paper, Triton X-114 was added to the sample for extraction of pramipexole from urine samples [36] .…”

In one paper, Triton X-114 was added to the sample for extraction of pramipexole from urine samples [36] . Triton X-114 is a non-ionic surfactant, and extraction of pramipexole increased with increased concentration of surfactant in the sample up to about 0.2 mM.…”

Electromembrane extraction (EME) is an analytical microextraction technique, where charged analytes (such as drug substances) are extracted from an aqueous sample (such as a biological fluid), through a supported liquid membrane (SLM) comprising a water immiscible organic solvent, and into an aqueous acceptor solution. The driving force for the extraction is an electrical potential (dc) applied across the SLM. In this paper, EME is reviewed. First, the principle for EME is explained with focus on extraction of cationic and anionic analytes, and typical performance data are presented. Second, papers published in 2016 are reviewed and discussed with focus on (a) new SLMs, (b) new support materials for the SLM, (c) new sample additives improving extraction, (d) new technical configurations, (e) improved theoretical understanding, and (f) pharmaceutical new applications. Finally, important future research objectives and directions are defined for further development of EME, with the aim of establishing EME in the toolbox of future analytical laboratories.

Analysis of biological samples is affected by interfering substances with chemical properties similar to those of the target analytes, such as drugs. Biological samples such as whole blood, plasma, serum, urine and saliva must be properly processed for separation, purification, enrichment and chemical modification to meet the requirements of the analytical instruments. This causes the sample preparation stage to be of undeniable importance in the analysis of such samples through methods such as microextraction techniques. The scope of this review will cover a comprehensive summary of available literature data on microextraction techniques playing a key role for analytical purposes, methods of their implementation in common biological samples, and finally, the most recent examples of application of microextraction techniques in preconcentration of analytes from urine, blood and saliva samples. The objectives and merits of each microextration technique are carefully described in detail with respect to the nature of the biological samples. This review presents the most recent and innovative work published on microextraction application in common biological samples, mostly focused on original studies reported from 2017 to date. The main sections of this review comprise an introduction to the microextraction techniques supported by recent application studies involving quantitative and qualitative results and summaries of the most significant, recently published applications of microextracion methods in biological samples. This article considers recent applications of several microextraction techniques in the field of sample preparation for biological samples including urine, blood and saliva, with consideration for extraction techniques, sample preparation and instrumental detection systems.

The current article is focused on introduction and validation of electro‐membrane extraction along with a high‐performance liquid chromatography combined with UV detector for the identification of the antiepileptic drugs phenytoin (PT) and phenobarbital (PB) in plasma, saliva, and urine. In addition, 3D‐printing was utilized to fabricate the designed caps required for fixing the electrodes in the prepared setup, giving us a high potential in device fabrication with various dimensions. To arrive at the highest extraction of PB and PT, the parameters impacting the extraction efficiency of electromembrane extraction for example, supported liquid membrane composition, sample solution pH, applied voltage, extraction time along with effect of graphene oxide are examined in detail. In optimized experimental conditions, the calibration plots were obtained to be linear on the concentration range of 25–500 ng/L with the detection limit and quantitation limit of 7.5 and 25 ng/L for both of PB and PT. Relative standard deviations of <9.9% and <9.1% were found for PB and PT, respectively and the enrichment factor for the presented method was computed to be 25.4 and 44.7 for PB and PT, respectively. The proposed method was satisfactorily employed in determination of PB and PT in plasma, urine and saliva.
