Stable Isotope Ratio Analysis (SIRA) is a powerful method to verify product provenance, detect mis-labelled products and identify fraud.


The strength of SIRA stems directly from the quality of the reference database. Open access is available to 61 of our reference databases.

We can verify the origin of over 100 different products

As one of the leading stable isotope testing service providers, we are continually looking for ways to deliver greater resolution.


Our results include up to 8 isotope signatures per sample - a more accurate result than we believe is available anywhere else.

What you can test

From apples to zucchini, we have signatures from reference samples sourced from around the world.

Meat and fish



Eggs and dairy

Vegetables, salads, cereals and grains

Processed products

Chemicals and flavourings

Non-food products
