Flow injection with an integrated retention/photometric detection unit for the determination of iron in water
(ACADEMIC PRESS INC JNL-COMP SUBSCRIPTIONS, 1996-05)
An integrated retention/photometric detection method for the determination of microamounts of iron was developed. The method is based on the retention of the reaction product of the analyte with ferrozine in a flow cell ...
INTEGRATED RETENTION SPECTROPHOTOMETRIC DETECTION METHOD FOR THE DETERMINATION OF FORMALDEHYDE
(MARCEL DEKKER INC, 1992)
An integrated-sensor method for the determination of formaldehyde based on retention of the reaction product of the analyte with p-rosaniline and sulfite in a flow-cell packed with Dowex 1-X-8 anion exchange resin was ...

(1992)
An integrated-sensor method for the determination of formaldehyde based on retention of the reaction product of the analyte with p-rosaniline and sulfite in a flow-cell packed with Dowex 1-X-8 anion exchange resin was ...
An on-line solid phase extraction system using polyurethane foam for the spectrophotometric determination of nickel in silicates and alloys
(1999)
The present paper describes the use of a solid phase extraction system using a polyurethane foam (PUF) minicolumn, in order to separate nickel from interferences due to other elements and determine it by flow injection ...
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 ...

A colorimetric iron sensor based on the partition of phenanthroline complexes into polymeric hydrogels: Combinatorial synthesis and high throughput screening of the hydrogel matrix
(Elsevier Science Sa, 2017-03)
A combinatorial library of hydrogels is produced by radical polymerization and tested for retention of iron (II) complexes, using a simple colorimetric high throughput screening (HTS). Six acrylamide monomers are used to ...
Dosagem de etanol utilizando alcool desidrogenase de levedura de panificação
(Universidade Estadual Paulista (Unesp), 2006-07-07)
O presente trabalho descreve e compara duas metodologias enzimáticas de dosagem de etanol (métodos UV e colorimétrico), que utilizam desidrogenase alcoólica (álcool: NAD+: oxidoredutase EC 1.1.1.1) de fermento de panificação ...
Emprego de padrão único para a construção de curvas analíticas em sistema de análise por injeção em fluxo associado à espectrofotometria em fase sólida
(2003)
In this work two procedures were proposed for analytical curves construction using a single standard solution employing a flow injection system with solid phase spectrophotometric detection (FI-SPS). A flow cell contends ...
