Mass spectrometry is one of the fastest growing sectors in analytics. JEOL has been supplying mass spectrometers for many fields of application for more than 50 years. The instruments are used for both simple, routine tasks, as well as for extremely demanding analyses. When developing these devices, particular attention was paid to robustness and the use of innovative technologies.
At the boundary between organic and inorganic chemistry, the organometallic compounds have unique properties that predestine them for use as catalysts or for epitaxial deposition. The analysis of the often temperature- or air-sensitive compounds poses a particular challenge for the measuring instruments. JEOL therefore supplies tailor-made mass spectrometers with specially developed ion sources.

Inorganic base materials form the basis of a number of important industrial intermediate and end products (e.g. plastics, dyes, fertilisers). These basic materials therefore already have to fulfil certain quality criteria. The powerful systems from JEOL enable the structural characterisation of such chemicals and thus make unequivocal statements regarding their composition and purity.

Organic basic chemicals are an elemental component of the manufacturing chemical industry. Precise molecular characterisation is essential for any further processing. Thanks to their diversity, the high-performance JEOL spectrometers are capable of quickly and efficiently resolving all structural questions.

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.

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.

The precise determination of gases with minimal differences in their atomic masses is an important task in the production of technical gases. It is not possible to exactly determine all the constituents of a gas mixture with conventional mass spectrometers. The special high-performance mass spectrometers from JEOL enable the determination and analysis of all gaseous, chemical compounds, including atomic hydrogen.

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.
