Work experience

Laboratory Technician (Sept 2020- Present day )
Mass Spectrometry Laboratory/ Organic Pollutants in the Aquatic Environment, IDAEA-CSIC. Barcelona, ​Spain.
❑ Analysis of organic pollutants in environmental samples by liquid chromatography coupled to both tandem mass spectrometry (LC-MS / MS) and high resolution (LC-HRMS).
Expertise:
✓ Reception and pretreatment of samples.
✓ Analysis of physico-chemical parameters (pH, conductivity, free chlorine, hardness).
✓ Preparation, extraction and purification of samples.
✓ Instrumental analysis by liquid chromatography coupled to mass spectrometry.
✓ Quantification and development of results.
✓ Reagent stock control.
✓ Waste management.
✓ Equipment calibration, verification and maintenance.
Analytical methodologies: Liquid-liquid extraction (LLE), solid phase extraction (SPE) both on-line and off-line, extraction in soxhlet of environmental samples from different sources (water, Granulated Active Coal (GAC) , urine or algae) for the analysis of per-fluorinated substances, toxins, pesticides, drugs and other emerging organic pollutants.
Instrumental techniques: Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) and highresolution liquid chromatography (LC-HMRS)
