A sensitive flow analysis system for the fluorimetric determination of low levels of formaldehyde in alcoholic beverages
(2007)
A sensitive FIA method was developed for the selective determination of formaldehyde in alcoholic beverages. This method is based on the reaction of Fluoral-P (4-amine-3-pentene-2-one) with formaldehyde, leading to the ...
On-line complexation/cloud point preconcentration for the sensitive determination of dysprosium in urine by flow injection inductively coupled plasma-optical emission spectrometry
(Springer Heidelberg, 2003-01)
An on-line dysprosium preconcentration and determination system based on the hyphenation of cloud point extraction (CPE) to flow injection analysis (FIA) associated with ICP-OES was studied. For the preconcentration of ...

Determination of Azithromycin by an alternative FIA amperometric method for different pharmaceutical applications
(American Chemical Society, 2013-03)
This work presents a fast and reliable electroanalytical procedure for the quantification of azithromycin (AZ) in different systems that couples flow injection analysis and amperometric detection (FIA-AM). The quantification ...
Carbon nanofiber screen printed electrode joined to a flow injectionsystem for nimodipine sensing
(Elsevier, 2015)
tA simple and sensitive electrochemical method using pretreated carbon nanofiber screen printed elec-trodes joined to a flow injection analysis (CNF-SPE-FIA) system was developed to analyze nimodipine(NMD) in pharmaceutical ...
