Simple and sensitive determination of sulfites in Chinese herbal teas by ultrahigh-performance liquid chromatography tandem mass spectrometry

Abstract

Sulfites are used widely in food and beverages production to prevent browning or oxidation. However,the overingestion of sulfites is harmful to human health and may cause medical complications. Chinese herbal...

Constructing graphene oxide/Au nanoparticle cellulose membranes for SERS detection of mixed pesticide residues in edible chrysanthemum

“…At present, the widely adopted methods for detecting pesticides in chrysanthemum still rely on GC-MS 17 and liquid chromatography-tandem mass spectrometry (LC-MS/MS). 18 For example, in a recent study, 6 types of pesticide residues in chrysanthemum were detected by GC-MS, including fenthion. 19 In another work, 27 pesticides including phoxim were analysed in chrysanthemum using the LC-MS/MS technique.…”

Electrocatalytic response of nitrogen-doped hollow carbon spheres modified glassy carbon electrode for sulphite detection in water

“…Excessive levels of sulphite in human body may be accompanied by nettle rash, swelling, headache, diarrhea, nausea, stomach irritation, and asthma episodes [7,8]. The sulphite determination has been carried out previously using diverse methods, including high-performance liquid chromatography [9], spectrophotometry [10], flow injection analysis [11], capillary electrophoresis [12] and electrochemical technique [13][14][15][16].…”

Fabrication of Versatile Fe3O4/GO/Au Composite Nanomaterial as SERS-active Substrate for Detection of Pesticide Residue

“…In recent years, there has been signi cant development in pesticide residue detection technology, leading to the proposal of various technical methods for detecting pesticide residue in fruits and vegetables (Łozowicka et al 2017). These methods include gas chromatography-mass spectrometry (Wang et al 2022), liquid chromatography-mass spectrometry (Yang et al 2022), immunoassay )and SERS. SERS is a rapid detection technique that has been utilized for food identi cation, quantitative detection, and classi cation of food pollutants.…”
