Integrated pressurized solvent extraction-cleanup for the rapid determination of polychlorinated biphenyls in meat samples
(SOC BRASILEIRA QUIMICA, 2013)
An overview of the main foodstuff sample preparation technologies for tetracycline residue determination
(2018-05-15)
Tetracyclines are widely used for both the treatment and prevention of diseases in animals as well as for the promotion of rapid animal growth and weight gain. This practice may result in trace amounts of these drugs in ...
Fully electrochemical hyphenated flow system for preconcentration, cleanup, stripping, capillary electrophoresis with stacking and contactless conductivity detection of trace heavy metals
(ELSEVIER SCIENCE INC, 2010)
Successful coupling of electrochemical preconcentration (EPC) to capillary electrophoresis (CE) with contactless conductivity detection (C(4)D) is reported for the first time. The EPC-CE interface comprises a dual glassy ...
