The above services are routinely undertaken and available immediately.
Use our quote form to obtain a price for isotope analysis of your samples.
Please contact us if the analyses you require are not listed.

Our laboratory is equipped with 5 modern continuous flow - isotope ratio mass spectrometers.
We can provide quick turn-around on both isotopically labelled and natural abundance samples.

The sample sizes given are for guidance purposes only.
Analysis by EA-IRMS will normally only consume 1 - 5 mg of sample material.
Unused sample material will be returned upon request.
The sample turnaround times given are typical for analysis of 50 samples.
