  • Thermal Desorption-GC/MS Analysis of polycyclic aromatic hydrocarbons on fine particulates in air

    Polycyclic aromatic hydrocarbons (PAHs) are commonly found throughout the environment in soil, water and adsorbed to fine particulate matter in air. Of the 16 common PAHs, 7 have been classified as animal carcinogens by the International Agency for Research on Cancer (IARC). Resulting from this classification, PAHs are monitored and regulated in the environment. Analysis of PAHs in soil and water ...

  • Gaseous release in LiNH2–MgH2 systems

    Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, ...

  • Enhanced separation of hop oils by flow-modulated GC×GC–TOF MS with Tandem Ionisation

    Beer contains hundreds of organic ingredients, with concentrations spanning many orders of magnitude, and including monoterpenes (C10) and sesquiterpenes (C15). These are aroma-active hydrocarbons found in the essential oils of various plants, including hops, and provide much of the characteristic ‘bitterness’ of the finished beer. Of the greatest importance for beer is the ...
