Determination of herbicides in surface water by means of a supported liquid membrane technique and high-performance liquid chromatography

On-Line Coupling of Flow Through Voltammetric Microcell to Hollow Fiber Permeation Liquid Membrane Device for Subnanomolar Trace Metal Speciation Measurements

“…Extensive work has been done to couple PLM with HPLC and UV-visible [20] and some work has been reported on its coupling to electrochemical detectors for analysis of organics in both biological and environmental samples [20][21][22][23][24][25][26][27]. In contrast, much less work has been described in the literature on the coupling of PLM to detectors for inorganic element determination [9,10,20,29].…”

Urine sample preparation of tricyclic antidepressants by means of a supported liquid membrane technique for high-performance liquid chromatographic analysis

“…Recently, the supported liquid membrane technique has been applied for the extraction of variety of environmental and biological samples, e.g. for the determination of metoxy-s-triazines in river water [12], amino acids [13][14][15], volatile organic acids in confined animal buildings [16], thiophanate-methyl and its metabolites in spiked water [17], cationic surfactant in waste water [18] and ropivacaine metabolites in urine [19], amphetamines in water and urine samples [20], amperozide by ASTED automated system [21], propazine and simazine in surface water [22] and diprivan in urine [23].…”

Analysis of Triazines and Associated Metabolites with Electrospray Ionization Field-Asymmetric Ion Mobility Spectrometry/Mass Spectrometry

“…10 SLM with LC separation and optical detection has been employed for triazines with LOD in the range 1 -30 ppt. [11][12][13][14][15][16] In immuno-SLM, antibodies situated in the acceptor, unable themselves to penetrate the membrane because of their size or because of being immobilized on magnetic beads, bind analytes, effectively trapping them there 17,18 with resulting enrichment factors of up to 2000. 19 The result for simazine (fluorescence detection) is an LOD of 0.01 ppt, ten thousand times better than what can be obtained with an analogous procedure but without the membrane.…”
