    Mercury monitoring for isotopic abundance by the ICP-MS

    Studies of real-world ecosystems are very complex. Mercury species inter-conversion as well as mercury deposition and evasion are constantly occurring. One technique to help sort out the processes is to trace reactions using natural Hg isotopes. Either by enriching a system with a particular isotope or determination of isotopic ratios as a technique of source identification, isotopes are a powerful tool for investigation. The Tekran 2600 Total Mercury and Tekran 2700 Methyl Mercury systems are designed to couple to an ICP-MS for mercury quantification by CVAFS and isotopic abundance by the ICP-MS.

    Gas analysis & monitoring system for food traceability

    Recognition of raw materials: The analysis of stable isotopes is very important especially in studies of authenticity of the food. It, on the basis of different isotopic ratio, allows to recognize molecules, present in foods, having the same chemical structure but coming from different raw materials or processed by different processes, for example for biological synthesis or industrial.

    Gas analysis & monitoring system for water - natural sciences

    In nature, the chemical elements can be represented by more isotopes, or atoms of the same element, characterized by a different number of neutrons in the nucleus. When the proton / neutron ratio does not exceed that value likely to upset the balance of the atom, resulting in the phenomenon known as stabilization of radioactive decay, the isotope is called stable. That is, over time, will not tend to emit energy and sub-nuclear particles to gain energy stability, giving rise, at the end of the process, the daughter nucleus (a different element, characterized by stability energy).
