Built around your method.
Every Sonnen instrument is specified against the published standard it must pass. Find your industry below; each lists the methods covered and the instruments we recommend for them.
Food & Feed
Crude protein by Kjeldahl, fiber by filter-bag and fat by solvent extraction — the three daily determinations of every food and feed laboratory.
Dairy
Nitrogen and protein in milk and milk products, including non-protein and casein fractions, against the ISO 8968 / IDF 20 series.
Soil & Agriculture
Total nitrogen in soil, plant tissue and agricultural inputs — high-throughput digestion blocks matched to automated distillation.
Water & Environment
Kjeldahl nitrogen and ammonium in water, plus COD by automated titration — unattended operation for monitoring workloads.
Fertilizer
The field Sonnen helped standardize: automatic nitrogen determination in fertilizers per GB/T 22923-2008, which the company co-drafted.
Rubber & Petrochemical
Nitrogen in raw natural rubber, fat and extractables in polymers and oils, and chloride-ion determination in construction materials.
