On-line extraction and determination of carbofuran in raw milk by direct HPLC injection on an ISRP column
(Vieweg, 1998-01-01)
A method has been developed for extraction and determination of carbofuran in milk. The method involved direct injection of raw milk on to a human serum albumin dimethyloctyl-silica gel (HSA-Cs) column and the use of 80:20 ...

Cloud-point extraction/preconcentration on-line flow injection method for mercury determination
(Elsevier Science, 2004-01)
A cloud-point extraction/preconcentration (CPE/P) step is incorporated on-line into a flow injection system which is used to determine low levels of Hg(II) added to natural water samples. The analyte is complexed with ...
Exploitation of a single interface flow system for on-line aqueous biphasic extraction
(ELSEVIER SCIENCE BV, 2010)
The exploitation of aqueous biphasic extraction is proposed for the first time in flow analysis This extraction strategy stands out for being environmentally attractive since it is based in the utilization of two immiscible ...
