The above geochemistry services 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.
