Development of a transportable High-Performance Liquid Chromatograph with Ultraviolet detection and a method for the rapid analysis of 13 carbonyl compounds hydrazones by Audrey Grandjean, Anaïs Becker, Mathilde Mascles, Franck Amiet, Jean-Philippe Amiet, Damien Bazin, Stéphane Le Calvé

“…Performances were close to that of the laboratory HPLCs, either in sensitivity, resolution, or repeatability with overall more accurate and robust results with the UV than with the LED detector. Despite the LED system not fully meeting the standard method requirements with linearities correlation coefficients lower than 0.999, both systems and methods were validated for the isocratic analysis of hydrazones for aldehydes and ketones quantification. …”

Development of a superheated water chromatography method for the sustainable determination of preservatives in foods and cosmetics by Roberta La Tella, Danilo Donnarumma, Francesca Rigano, Paola Donato, Patrik Appelblad, Paola Dugo, Luigi Mondello, Alice Mondello

“…Hardware modifications were also necessary to guarantee the efficient heating of the mobile phase prior of entering the column, as well as its rapid cooling before detection by photodiode array (PDA). Specifically, an LC system was interfaced to a GC oven, which hosted the LC column; to achieve a fast and efficient heating of the eluent coming from the autosampler prior to enter into the column, a pre-heating tube was interposed between the autosampler outlet and the column inlet. …”
