A Sensor-Based Methodology to Differentiate Pure and Mixed White Tequilas Based on Fused Infrared Spectra and Multivariate Data Treatment
(MDPI, 2021-02-27)
[Abstract]: Mexican Tequila is one of the most demanded import spirits in Europe. Its fast-raising worldwide request makes counterfeiting a profitable activity affecting both consumers and legal distillers. In this paper, ...
Fast Quality Control of Natural Gas for Commercial Supply and Transport Utilities
(Elsevier, 2021-07-28)
[Abstract] Quality control of natural gas frequently relies on off-line slow standardized chromatographic techniques. Previous implementations of new measurement approaches focused of synthetic mixtures without extensive ...
New Ways for the Advanced Quality Control of Liquefied Natural Gas
(MDPI, 2022-01-04)
[Abstract] Currently, gas chromatography is the most common analytical technique for natural gas (NG) analysis as it offers very precise results, with very low limits of detection and quantification. However, it has several ...
Study of Temporal Variations of Equivalent Black Carbon in a Coastal City in Northwest Spain Using an Atmospheric Aerosol Data Management Software
(MDPI AG, 2021-01-07)
[Abstract]
Light-absorbing carbonaceous aerosols (including black carbon (BC)) pose serious health issues and play significant roles in atmospheric radiative properties. Two-year measurements (2015–2016) of aerosol light ...
Evolution of Gaseous and Particulate Pollutants in the Air: What Changed after Five Lockdown Weeks at a Southwest Atlantic European Region (Northwest of Spain) Due to the SARS-CoV-2 Pandemic?
(MDPI, 2021-04-27)
[Abstract] Due to the exponential growth of the SARS-CoV-2 pandemic in Spain (2020), the Spanish Government adopted lockdown measures as mitigating strategies to reduce the spread of the pandemic from 14 March. In this ...
Levels and Sources of Atmospheric Particle-Bound Mercury in Atmospheric Particulate Matter (PM₁₀) at Several Sites of an Atlantic Coastal European Region
(MDPI, 2020-01)
[Abstract] Atmospheric particle-bound mercury (PHg) quantification, at a pg m⁻³ level, has been assessed in particulate matter samples (PM₁₀) at several sites (industrial, urban and sub-urban sites) of Atlantic coastal ...
Polycyclic Aromatic Hydrocarbons Analysis in Tea Infusions and Tea Beverages Using Membrane Assisted Solvent Extraction
(Elsevier, 2021-04-16)
[Abstract] Membrane Assisted Solvent Extraction (MASE) was applied as an extraction and enrichment technique of polycyclic aromatic hydrocarbons (PAHs) from tea infusions and fruit/herbal-tea beverages. PAHs have been ...
Development of a Fast and Efficient Method to Analyze Microplastics in Planktonic Samples
(Elsevier, 2021-04-22)
[Abstract] Microplastics (MPs) affect plankton (a basis of the trophic chain) and planktivorous fish can ingest them through food confusion or by trophic transmission. Consensus to determine MPs in plankton is lacking and, ...
Monitorization of Polyamide Microplastics Weathering Using Attenuated Total Reflectance and Microreflectance Infrared Spectrometry
(Elsevier, 2021-07-10)
[Abstract] The EU goal to reduce marine plastic litter by ca. 30% by 2020 stressed the need to deploy analytical methods to ascertain the polymeric nature of a residue. Furthermore, as plastics age under natural conditions ...
Development and Validation of a Multi-Pollutant Method for the Analysis of Polycyclic Aromatic Hydrocarbons, Synthetic Musk Compounds and Plasticizers in Atmospheric Particulate Matter (PM₂.₅)
(Elsevier, 2021-07-18)
[Abstract] Exposure to atmospheric particulate matter (PM) associated pollutants is a global concern due to the risk posed in human health after inhalation. In this study, a simple and sensitive multi-residue method is ...
