Dear All I am looking for quotes to perform C and H isotope analyses on solvent extracted n-alkanes from terrestrial sediments from around the PETM. We have preformed the extractions ourselves and have GC traces showing good separation of n-alkanes in the range n-C23 to n-C31, with a odd over even predominance. If your lab have experience of performing such analyses and are able to analyse approximately 50 of our samples then could you please contact me offline with a quote per sample. Many thanks Steve ------------------------------------------------------------------------------------------------------------------------------------------------------------ Dr. Stephen Grimes Lecturer in Stable Isotope Geochemistry & Climate Change School of Earth Ocean and Environmental Sciences University of Plymouth Drake Circus Plymouth Devon PL4 8AA Office: Room 120 Fitzroy Building Tel. +44 (0)1752 233109 (internal ext. 33109) Fax. +44 (0)1752 233117 e-mail: [log in to unmask]<mailto:[log in to unmask]> Personal Professional Page<http://www.plymouth.ac.uk/pages/dynamic.asp?page=staffdetails&id=sgrimes> Palaeontology & Palaeoenvironments Research Group<http://www.research.plymouth.ac.uk/paleopalenv/MICROPAL.html>
