Quality Testing

Personalized Service Since 1982

Locally owned in southern Michigan, Litchfield Analytical Services has built a solid reputation in the Midwest for quality testing, personalized service, and quick turnaround. We are committed to maintaining this reputation as we grow. LAS offers testing for many varieties of samples—feed, forage, grain, soil, greenhouse media, fertilizer, manure, lime, water, plant tissue, and even lawn/garden.

Our staff is trained and experienced which ensures accurate and reliable results. We use modern, well-maintained, and daily-calibrated equipment to perform valid analytical procedures as prescribed by the Association of Official Analytical Chemists (AOAC). Standard operating procedures include precautions to prevent contamination and provide a safe working environment.
