Isotopic tracer activity using isotopic variations of strontium, copper, iron, zinc, calcium
or lead is now well recognized and we can offer you an analytical quality service on
all types of samples (soil, water, food for human or animals...).
Nevertheless in the food field one must take precautions. Indeed, the use of a tracer is quite complex because we are going to add a metallic element (ie Cu, Zn etc out of C, H, N, O) with an unnatural isotopic abundance that should be reflected in animals and foods tracing. This technique is not new as it was used in the 80's and was even patented. Since the patent has not been renewed and is therefore free of rights. In fact, most animals have foods with various additions of metals to improve their performance like calcium, strontium, sodium, magnesium and especially copper, iron or zinc. These additions would therefore be the easiest way to use because the first approach would be to modify the isotopic ratios of these elements when creating food and thus obtain animals with modified isotopic ratios and therefore traceable. Unfortunately, this is not possible because over the past 10 years, dozens of laboratories around the world have shown that the isotopic ratios of copper, iron, zinc, calcium or magnesium can be used as biomarkers for a number of diseases ranging from cancers, SLA, osteoporosis or other neurodegenerative diseases etc ....
Modification of the isotopic ratio for these very important element in the diet will inevitably cause a change in the values obtained on humans and in this case we would be totally in an unknown trip at the medical level and it is therefore not possible to use this route.
We preferred a different way by using an element that we can not reveal for the moment but which has two main characteristics, the first one is that it is almost not metabolized by the animals and thus remains in the trace state in the meat produced. In that case, a modification of its isotopic ratio will not cause any change in the isotopic ratio in humans because the source for the human does not come from the diet but more from vegetables or sea food. Secondly, its cost is almost 100 times lower than that of the other major elements like copper, zinc or iron, the needed level is low due to it's trace concentration and is therefore not a barrier to its masssive adoption.
We have also developed a new tracer (DBisoTRACE patent pending) which is added
to fuel oil to prevent fraud (red vs normal) and which has the advantage of not being
able to be removed once integrated. A trace will remain whatever the chemical
treatments that can be implemented.
We can study all types of matrix or objects requiring robust tracing.
We can also help for technology transfert for analytical measurements, isotopic pathways
understanding for differents types of matrixes or samples.
The analysis of major and trace metals in all types of matrices is also a benefit that
we can offer.
