Construção e aplicação de uma cela espectrofotométrica de camada delgada para análises em fluxo Construction and application of a thin layer spectrophotometric cell for flow analysis

Autor: Paulo C. C. de Oliveira, Vitor J. P. Gouveia, Jorge C. Masini

Publikováno v: Química Nova, Vol 24, Iss 3, Pp 399-403 (2001)

A low cost spectrophotometric cell for use in flow analysis was manufactured in acrylic and adapted to a commercial spectrophotometer. The application of this cell was performed in the determination of chromium (VI) in steel samples using the reactio

A new spectroelectrochemical cell for flow injection analysis and its application to the determination of Fe(II) down to the femtomol level by surface-enhanced resonance Raman scattering (SERRS)

Autor: Joel C. Rubim, Ivano Gebhardt Rolf Gutz, Vitor J. P. Gouveia

Publikováno v: Journal of Electroanalytical Chemistry. 371:37-42

A spectroelectrochemical cell that uses surface-enhanced Raman scattering (SERS) for detection in flow injection analysis (FIA) is presented. The SERS-active surface is generated in situ by the electrochemical deposition of a silver film on a glassy
