Development of analytical applications of liquid chromatography (HPLC).
Physico-chemical characterisation of mural painting from the Maya Lowlands. Bank with more than 300 samples from murals that decorated the Mayan palaces of Yucatan and Campeche (Mexico) and Petén (Guatemala). Elaboration of the database "Materials and techniques of Maya mural painting".
Physico-chemical characterisation of the substances that were used in the ancient cultures of Mesoamerica to prepare the body pigments and aromas used by the upper social classes, which had great aesthetic, symbolic and ritual importance.
Classical methods to characterise chromatographic columns are based on the measure of retention and the use of a selected group of compounds. The validity of these approaches is investigated and new, more reliable strategies based on retention, selectivity and peak shape are proposed.
The objective of this line of research is the design, development, validation and application of analytical methods for safety evaluation studies of cosmetic ingredients in relation to percutaneous absorption and excretion processes in the human body.
The objective of this line of research is the design, development, validation and application of analytical methods to carry out studies to evaluate the environmental impact of cosmetic products and in particular of ingredients considered to be emerging pollutants.
The objective of this line of research is the design, development, validation and application of analytical methods to control cosmetic products and their raw materials in order to guarantee their quality and fulfilment of current legislation.
The objective of this line of research is the design, development, validation and application of analytical methods based on the use of microextraction techniques that allow the analysis of samples with complex matrices without interferences and with high sensitivity.
Based on the fundamental advances in HPLC made by the research group, analytical methods for several samples in the pharmaceutical, clinical and food fields are designed. Method development is accompanied by an extensive validation.
Research and development of high-throughput (bio)analysis methods (Liquid chromatography, Capillary electrophoresis, Mass spectrometry) for the separation and determination of molecules (including chiral) with analytical and bioanalytical applications. (Bio)sensors.
Commercially available RPLC columns do not allow the analysis of charged or highly polar compounds. A line is developed to improve chromatographic performance using secondary equilibria, with special emphasis on the addition of surfactants and ionic liquids to the mobile phase.
