Improved intracellular PHA determinations with novel spectrophotometric quantification methodologies based on Sudan black dye
(Elsevier Science, 2018-05)
The presence of intracellular polyhydroxyalkanoates (PHAs) is usually studied using Sudan black dye solution (SB). In a previous work it was shown that the PHA could be directly quantified using the absorbance of SB fixed ...

Flow injection spectrofluorimetric determination of carvedilol mediated by micelles
(Elsevier Science, 2008-06)
A novel flow injection (FI)-spectrofluorimetric methodology for the determination of carvedilol in microheterogeneous medium has been developed. In the sodium dodecyl sulfate (SDS) surfactant medium, an additional fluorescence ...
Evaluation of quartz tubes as atomization cells for gold determination by thermospray flame furnace atomic absorption spectrometry
(Pergamon-Elsevier Science Ltd, 2012-11)
This work describes the development of a new analytical procedure able to determine gold by thermospray flame furnace atomic absorption spectrometry (TS-FF-AAS) using nickel tubes (NiT) and quartz tubes (QT) as atomization ...
Simple-to-use and portable device for free chlorine determination based on microwave-assisted synthesized carbon dots and smartphone images
(Elsevier Science, 2021-07-01)
A new portable and simple 3D printed device was designed for free chlorine determination in water samples. The analytical method was based on the quenching caused by free chlorine on the fluorescence emission of the carbon ...
