Given the recent discussions on "organic carbon" I thought my query would be appropriate for this list. I am interested in contracting out some work for soil and sediment analysis of total carbon with laboratories that use dry combustion methodologies - insturmentation such as Carlo-Erba, LECO or similar are preferred. I'd appreciate receiving addresses for university geochemical labs offering such services. Reply directly to me e-mail address rather to the Listserv - thanks for your input. R.
