The above services for Agricultural and Environmental Science are routinely undertaken and available immediately. 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 40 samples.

Please contact us if the analyses you require are not listed.
