A wide variety of contaminants with the potential to cause harm to humans and animals can make their way into the environment. They can be found in the air, water and soil and may come from sources such as industrial waste, landfill sites, pesticides and pharmaceutical drugs. Identifying these contaminants is challenging because of the huge variety of potential compounds with varying chemical compositions. These challenges call for sophisticated analytical techniques, such as Orbitrap-based high-resolution mass spectrometry, which provide distinct advantages.
In this new eBook we bring together some of the key application notes, written in collaboration with scientists from around the world, which demonstrate how GC-Orbitrap™ makes a real difference to environmental analysis.
Articles included are:
