Compositional Analysis

Bigelow Laboratory offers comprehensive compositional analysis to quantify the physical, chemical, and nutritional makeup of biological and non-biological samples. These measurements provide critical insight into ecosystem function, energy flow, organismal health, and biological responses to environmental change.

Our services include determination of ash content, caloric value, macronutrient profiles (carbohydrates, proteins, fats), elemental composition, fatty acid signatures, and stable isotopes to help quantify organismal health, productivity, and trophic dynamics — all foundational information for both basic research and applied environmental management.

Services Available:

• Ash content
• Caloric content
• Carbohydrate content
• Elemental mass and ratios (C, H, N, S, O)
• Fatty acid
• Protein content
• Stable isotopes (13C and 15N)
