Quantification by SIFT-MS of volatile compounds produced by the action of sodium hypochlorite on a model system of infected root canal content

“…Sodium hypochlorite (NaOCl) is one of the of the most widely practised public health components of disinfection of drinking water, sewage-water plants, water supply and distribution systems, swimming pools and industrial applications with the aim of preventing the spread of infection and contamination [ 1 , 2 ]. Chlorination can kill the majority of bacteria, viruses and parasites responsible for waterborne diseases [ 3 ], as a strategy to meet the drinking water quality standards and disinfect waste water [ 4 , 5 ].…”

Ex vivo detection and quantification of apically extruded volatile compounds and disinfection by-products by SIFT-MS, during chemomechanical preparation of infected root canals

“…Sodium hypochlorite (NaOCl) is one of the of the most widely practised public health components of water disinfection to prevent the spread of microbial or viral diseases and contamination [1,2]. Despite its importance, chlorination of water for disinfection purposes may result in the formation of potentially harmful halogenated disinfection by-products (DBPs), due to the reaction of chlorine or hypochlorite with natural organic matter (NOM) [3].…”

A reference isotope dilution headspace GC/MS method for the determination of nitrite and nitrate in meat samples

“…To date, most popular methods for simultaneous determination of nitrite and nitrate are based on liquid separation. Della Betta et al , proposed an elegant capillary zone electrophoresis (CZE) method with UV detection, which could provide results within 30 s. Although CZE is a well‐suited technique for inorganic anions, CZE instruments are not widely diffused in testing laboratories and current methods for nitrite and nitrate mostly employ ion chromatography and C 18 reverse phase HPLC with conductivity (Iammarino & Di Taranto, ; Lopez‐Moreno et al , ; D’Amore et al , ), UV (Siu & Henshall, ; Hsu et al , ; Chetty et al , ) or mass spectrometry detection (Saccani et al , ; Siddiqui et al , ) although direct LC/MS methods for nitrite and nitrate are more commonly applied to simpler sample matrices (Khan et al , ; Khan et al , ). Despite such methodologies have reached a broad diffusion in food testing laboratories, liquid chromatography is typically lengthy (20–30 min per sample) and require a certain level of maintenance due to the complexity of the meat matrix.…”
