Soil, Sludge & Sediment

Soil, sludge, and sediment are commonly analyzed in environmental studies, agriculture, and waste treatment processes. Their composition provides insights into contamination levels, nutrient availability, and the impact of human activity on natural systems.

Velp offers advanced solutions for the analysis of solid and semi-solid environmental samples. Our instruments support laboratories, environmental agencies, and consultants in obtaining reliable and reproducible data across a wide range of parameters.

We support public and private entities in:

Elemental analysis for Total Nitrogen (TN), Total Carbon (TC), and Total Organic Carbon (TOC) content.
Kjeldahl analysis for nitrogen determination in soil fertility studies.
Extraction of oil, grease, and contaminants (e.g., PCBs).
Soil respiration tests: microbial respiration, biodegradability of plastic material in soil.
Biochemical Methane Potential (BMP) in sludge.
