Tracing the geographical origin of Argentinean lemon juices based on trace element profiles using advanced chemometric techniques
This study examines the application of chemometric techniques associated with trace element concentrations for origin evaluation of lemon juice samples. Seventy-four lemon juice samples from three different provinces of ...
Multivariate classification of honeys from Corrientes (Argentina) according to geographical origin based on physicochemical properties
Honey is the natural sweet substance produced by Apis mellifera bees and is studied in different countries and zones because of the interest of consumers in origin and quality of food. The Corrientes Province (Argentina) ...
Chemometric optimization and validation of a novel dispersive liquid liquid microextraction HPLC method for gliclazide, glibenclamide and glimepiride quantitation in serum samples
A dispersive liquid–liquid micro extraction (DLLME) liquid chromatographic method that allows extraction and separation of gliclazide, glibenclamide and glimepiride from serum was developed and optimized with the use of ...
Classification of organic olives based on chemometric analysis of elemental data
The aim of this study was to discriminate organic from conventional olive samples based on the levels of macro and trace elements, combined with chemometric techniques. Ten elements (Na, K, Ca, Fe, Mg, Cu, Zn, Se, S and P) ...
