Healthy food and a clean environment are two topics of relevance to us as a society every day. Furthermore, the topic of recycling in particular plays a significant role in terms of a sustainable economy. In these fields, the precise characterisation of materials is of crucial importance.
JEOL supplies solutions for environmental analysis, e.g. asbestos identification or trace analytics, as used to providing evidence of harmful substances in foodstuffs, for example.
Asbestos was used for decades as a fire- and temperature-proof raw and insulation material. Once the health risks were discovered, many laboratories examined potentially asbestos-containing construction materials. JEOL is the only manufacturer to offer the powerful combination of its own electron microscopes and own spectrometers as a complete solution for standards-compliant asbestos analysis.

These days, biocides are used extensively for pest control in agriculture. The quantitative determination of the toxic residues of the applied pesticides is of vital importance for the authorisation of agricultural products. JEOL high-resolution analytical instrument are capable of detecting biocides quickly and simply, even with the smallest of concentrations.

Fibres are used in many branches of industry, e.g. in textile processing or as a structural material in mechanical engineering. Their structural properties can be studied by means of a fibre cross-section, for example. JEOL supplies an established and powerful complete solution for simple, artifact-free preparation and high-resolution imaging and analytics.

Fossil fuels such as Diesel are highly complex mixtures of a wide range of linear, cyclic and aromatic hydrocarbons. Separating theses and thus unequivocally determining the constituents of the fuel is therefore of crucial importance. The combination of special, two-dimensional GC techniques allows JEOL systems to quickly deliver exact structural information.

As a widespread fuel, petroleum comprises a mixture of liquid hydrocarbons. It is very difficult to perform molecular analysis on it with standard mass spectrometric methods. JEOL systems are capable of determining the molecular weight without fragmentation in a quick, uncomplicated manner by soft ionisation.
