Journal ArticleDOI
Analysis of sudan I, sudan II, sudan III, and sudan IV in food by HPLC with electrochemical detection: Comparison of glassy carbon electrode with carbon nanotube-ionic liquid gel modified electrode
TL;DR: A method was developed by high performance liquid chromatography coupled with an electrochemical detector that could be applicable for the assay of sudan dyes in soft drink samples and obtained highly reproducible, well-defined cyclic voltammograms for sudan oxidation.
Journal ArticleDOI
Applications of everyday IT and communications devices in modern analytical chemistry: A review.
TL;DR: This paper reviews the development and recent use of everyday communications and IT equipment as detection devices for colorimetric chemistries and offers many opportunities in the areas of point of care diagnosis, and at-site monitoring of environmental, agricultural, food and beverage parameters.
Journal ArticleDOI
Fast and simultaneous detection of heavy metals using a simple and reliable microchip-electrochemistry route: An alternative approach to food analysis.
TL;DR: The results obtained allow the proposed microchip CE-ED acts as an alternative approach for metal analysis in foods as well as the potential and future role of micro chip CE, analytical possibilities and a new route in the raw sample analysis.
Journal ArticleDOI
Simple flow-injection system for the simultaneous determination of nitrite and nitrate in water samples
TL;DR: The proposed spectrophotometric flow-injection system coupled with a copperised cadmium reductor column could be applied successfully to the simultaneous determination of nitrite and nitrate in water samples.
Journal ArticleDOI
