We offer a complete project management and consultancy service from study conception to management of the analytical program, QC of data and presentation of results to clients and partners. The company was founded in 2001 to continue the business of Isotopic Analytical Services (IAS Ltd). We outsource all data acquisition to laboratories which we consider to be the best equipped to provide us with reliable data at reasonable cost and on time. All our radiogenic isotope analyses are performed by Macaulay Enterprises Ltd, a commercial arm of the Macaulay Institute, Aberdeen, where we are based.
