HPTLC-Densitometry Screening and Mass Identification of Fluorescent Whitening Agents Contamination in Cereal Flour

Identification of Fluorescent Brighteners as Another Emerging Class of Abundant, Ubiquitous Pollutants in the Indoor Environment

“…Fluorescent brighteners (FBs), also known as optical brighteners, fluorescent brightening agents, or fluorescent whitening agents, are a very important class of chemicals in the dyestuff industry widely added in textiles, paper products, plastics, detergents, soaps, paints, coatings, and cosmetics. − In addition, FBs have been illegally added to wheat flours, rice, and food packaging materials. − FBs are used to enhance the optical impression of whiteness and brightness of industrial products. The production of FBs can be traced back to the 1960s, and thus, they have a history spanning over 60 years .…”

Bio-screening and quantification of methyl paraben in vinegar and coconut juice separated by HPTLC

“…High performance thin-layer chromatography (HPTLC) platformed detections as a hyphenation technology enabled a new chance for analytical chemistry [5][6][7] , because it provides an excellent tool for screening the analyte in samples that were difficult for traditional methods based on column chromatography [8][9][10][11] . First, this hyphenation technology inherits the essential advantages of HPTLC like high throughput and matrix-tolerance [8,[12][13][14] . A single separation of many samples can be performed simultaneously.…”
