Narrowing the interface between sample preparation and electrochemistry: Trace-level determination of emerging pollutant in water samples after in situ microextraction and electroanalysis using a new cell configuration
(2018-06-10)
In this work, a new cell configuration that enables the in situ integration of sample preparation and electrochemical detection prior analysis at trace-level is described. To perform the microextraction, a green chemistry ...
PEPTIDE IN CAPACITANCE ELECTROANALYSIS FOR DIAGNOSTICS
(Wiley-Blackwell, 2016-09-01)
Sample preparation combined with electroanalysis to improve simultaneous determination of antibiotics in animal derived food samples
(2018-06-01)
A procedure based on liquid–liquid extraction (LLE) and phase separation using magnetically stirred salt-induced high-temperature liquid-liquid extraction (PS-MSSI-HT-LLE) was developed to extract and pre-concentrate ...
Simultaneous separation and electroanalysis in a single polydimethylsiloxane-based platform
(2021-10-01)
Channel-based microfluidic devices integrating the separation step and detection system are key factors to expand microanalysis application. However, these devices still depend on macroscale external equipment for pre-treatment ...
Electrochemical cell designed for in situ integrate microextraction and electroanalysis: Trace-level determination of norfloxacin in aqueous samples
(2019-05-01)
In this work, a newly designed electrochemical cell was assembled for in situ integrated microextraction and electroanalysis. Ionic liquids (ILs) were used as extractors to perform the microextraction, which enabled the ...
