Who are we?

We are Advanced Isotopic Analysis (AIA), a European company located in Pau, in the south-west of France. We combine internationally recognized  scientific expertise with strong business experience, using high-end equipment to deliver bespoke, high-precision analysis services to businesses worldwide. 
Our company is the result of a unique alliance between two experienced researchers in analytical chemistry - the French National Scientific Research Center (CNRS) and the University of Pau et des Pays de l’Adour (UPPA), as well as former Directors of a successful international company dedicated to the production of scientific instrumentation.

How can isotopic signatures
identification help? 

our mission

Environmental issues

Our team of specialists have extensive experience when it comes to environmental analysis, accurately tracking the origin of any contaminations present. 
This is particularly the case for elemental contamination, such as Mercury (Hg) or Lead (Pb), or when using other elements and their isotopes. 

Authentication and traceability of products

The intrinsic isotopic signatures of your product can be used to trace its primary origin and also authenticate the specific processes applied to your products. Thanks to our in-house research and development teams, we can develop bespoke analytical methodologies to suit your exact needs, helping to address traceability issues, fight fraud and validate local origins.

How the process works? 

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%).
