Sample submission and pricing
We accept samples from external researchers for stable isotope analyses in various environmental samples for geoscience research, and also for C, H, N, and S analyses in solid materials from other disciplines (Botany, Material Science, and Chemistry). We accept samples from the external users for the analyses types listed below. Contact us for special analysis requirements and/or sample types, pricing and other sample submission instructions.
Each batch of samples submitted for analysis must accompany a submission form with full details of the project chart-string (for Northwestern users) or billing information of external users.
