Our Method
What is an isotopic signature?
Molecules are composed of certain chemical elements, each of which has a unique isotopic composition. Thanks to this isotopic signature, we are able to determine with high precision and accuracy the origin, age and/or processes undergone by an element.
The natural isotopic compositions of a product are the results of different external parameters, such as its primary origin and the physical, chemical or biological processes that affect it. These factors can act as a marker of origin and gives extensive indications as to the history of a product.
All the information needed to track the origin is already present in your product.
Which isotopes can be analysed?
We offer analysis on “non-traditional” stable isotopes from elements such as Mercury (Hg), Lead (Pb), Strontium (Sr), Iron (Fe), Copper (Cu), Lithium (Li) or Boron (B). However, this is a non-exhaustive list, so whatever your request, we will be happy to help.
The team here at Advanced Isotopic Analysis has a specific expertise with heavy elements - particularly Mercury (Hg). For this last example, this means we can propose reliable analyses able to precisely track Mass Dependent Fractionation (MDF) and Mass Independent Fractionation (MIF) processes. These specific signatures allow a better understanding of both sources and pathways of Mercury (Hg) in the environment.
Furthermore, we have a world-leading level of know-how and analytical methodologies, allowing us to provide accurate and precise analysis, no matter the situation. This includes offering high-precision measurements, working with very small samples or at very low concentrations - we can even measure the isotopic signature of Mercury (Hg) in rain water.
Elemental concentrations
Prior to isotopic analysis, it is first necessary to determine the precise concentration of the targeted element.
Our team is able to deliver quantitative trace element analysis, which can also be used as a complementary tool to characterize processes and origins.
All samples are analysed for total metal concentration prior to checking for isotopic selective signatures.
Mass spectrometry techniques
We are equipped with high-end ICP-MS spectrometers (Inductively Coupled Mass Spectrometry), Quadrupole ICP-MS (ICP-QMS) and multi-collector ICP-MS (MC-ICP-MS).
The ICP-QMS is used to determine elemental concentrations, whereas the MC-ICP-MS, following careful sample purification, allows for measuring the isotopic composition with ultimate precision (down to 0.003%).
