“…14,15 HPLC-PAD is already commonly used for the detection of carbohydrates, 16 flavonoids, 17,18 lignans, 19 amino acids without derivatisation, and gluconic acid, 20 while CAD is used for carbohydrates. 21,22 With the aim of investigating whether sugar dosage using IC-PAD-CAD in combination with isotope ratios are useful for improving the detection of exogenous sugar addition to ABM must in "Aceto Balsamico di Modena IGP," a specific experimental design was set up. The major and minor sugar profiles of a wide selection of authentic Italian grape musts were investigated to identify the natural range of variability.…”

"Aceto Balsamico di Modena" (ABM) is a protected geographical indication salad dressing obtained from cooked and/or concentrated grape must, with the addition of wine vinegar and a maximum of 2% caramel (EU Reg 583/2009). In this study, we investigated whether the combination of C/ C of ethanol using isotope ratio mass spectrometry with H-site-specific natural isotope fractionation-nuclear magnetic resonance and minor sugars using ion chromatography with pulse amperometric and charged aerosol detection is able to improve detection of sugar addition to ABM must. A large selection of authentic Italian grape musts and different samples of balsamic vinegar with an increasing percentage of added beet, cane, and sugar syrups were considered. The possible degradation of sugars in the ABM matrix during shelf life was also investigated. While stable isotope ratios analysis remains the favoured method for determining cane and beet sugar addition, dosage of minor sugar (in particular maltose) proved to be very useful for detecting the addition of sugar syrup. Thanks to this innovative approach, 3 out of 27 commercial ABMs were identified as adulterated. A combination of stable isotope ratio and ion chromatography with pulse amperometric and charged aerosol detection analysis can be therefore proposed as a suitable tool for detecting the authenticity of ABM must.

“…So it is vital significance that H 2 O 2 level could be exactly and rapidly detected. Up to now, numerous detection techniques such as highperformance liquid chromatography [5], fluorescence [6], spectrophotometry [7], chemiluminescence [8], and electrochemistry [9][10][11] have been developed for monitoring H 2 O 2 . Among these methods, electroanalytical method has been widely used for accurate determination of H 2 O 2 owing to its simplicity, low cost, high sensitivity, low detection limit and the possibility for real-time detection.…”

“…The most popular direct detection modes are refractive index, evaporative light scattering [14][15][16], charged aerosol [17], and when high sensitivity is needed, pulse electrochemical detection [18,19]. More selective and sensitive detection can also be reached by fluorescence after derivatization with a fluorophore (e.g.…”

Analysis of underivatized cellodextrin oligosaccharides by capillary electrophoresis with direct photochemically induced UV‐detection

Analysis of underivatized cellodextrin oligosaccharides by capillary electrophoresis with direct photochemically induced UV-detectionThis work focuses on the development of a CE method allowing, for the first time, the simultaneous separation of the underivatized first seven cellodextrin oligomers (glucose, cellobiose, cellotriose, cellotetraose, cellopentaose, cellohexaose, and celloheptaose), with a view to analyze the hydrolysates obtained after partial acid depolymerization of nitrocellulose, and eight carbohydrates (ribose, xylose, fructose, mannose, galactose, maltose, lactose, and sucrose), which might be potential interfering compounds in explosives samples. Separation was achieved with a highly alkaline BGE containing sodium chloride and direct mid-UV-absorbance detection was performed after photo-oxidation in the detection window. EOF was reversed to speed up the analysis using a dynamic capillary coating by hexadimethrine bromide. A central composite design was carried out to determine the effects of BGE conductivity and sodium hydroxide concentration on resolutions between neighboring peaks, and analysis time. A desirability analysis on modeled responses was applied to maximize resolutions and to minimize analysis time. The simultaneous analysis in 20 min total runtime of the 15 carbohydrates plus internal reference (naphthalene sulfonate) was carried out at 25°C with a BGE composed of 77.4 mM NaOH and 183 mM NaCl to adjust the conductivity at the optimum value. Finally, the resolution robustness was checked. This new method should also be of interest to monitor food and nonfood crop products.

They are also widely used as food or beverage additives. This class of compounds of tremendous complexity actually encompasses a variety of molecules differing in size (mono-, oligo-, and polysaccharides), epimerization or isomerization, glycosidic linkage, branching, and functionality , and mixed modes [11,13] have all been commonly employed. Separations have been based on hydrogen bonding, size, complexing ability, and in some cases charge. As far as detection is concerned, great difficulties are encountered due to the lack of a chromophoric moiety. According to the sensitivity requirements and separation mode, different detection strategies have been implemented, namely, without-or with pre-or postcolumn
