Glycine functionalized multi wall carbon nanotubes as a novel hollow fiber solid phase microextraction sorbent for preconcentration of venlafaxine and o- desmethyl venlafaxinein biological and water samples prior to determination by high performance liquid
A hollow fiber solid phase microextraction method for preconcentration of venlafaxine and o-desmethylvenlafaxinein biological matrices is described for the first time. The functionalized MWCNTs with an amino acid,glycine, were synthesized and held...
Preconcentration of morphine in urine sample using a green and solvent-free microextraction method
The ability of extraction and preconcentration of small amounts of substances from biological samples is very important in medical toxicology. On the other hand, minimal use of organic solvents is an important ...
Design, synthesis and evaluation of a molecularly imprinted polymer for hollow fiber–solid phase microextraction of chlorogenic acid in medicinal plants
In this study, a simple preparation approach was developed for modified bisphenol A (BPA) molecularly
imprinted polymer sorbent used in the hollow fiber solid phase microextraction (MIP-HF-SPME)
of chlorogenic acid (CGA). The pre...
Potential application of amino acids in analytical toxicology
The ability of extraction and preconcentration of small quantities of substances from biological samples is important
in analytical sciences, particularly forensic medicine. In the present study, we evaluated the ...
Carbon nanotube assisted sol-gel based hollow fiber solidphase microextraction combined with pre-heating injectionhigh performance liquid chromatography as a novel sample preparation method for determination of nitroaromatics
fiber. This device has been applied for the determination of three nitro aromatic compounds, including m-nitroaniline (NA), nitrobenzene (NB) and p-nitrotoluene (NT), in environmental waters via direct immersion hollow fiber solid-phase microextraction...
