Food, Feed & Agriculture
Analytical reagents, pesticide-residue solvents and instrumentation for food safety and agricultural testing laboratories.
Food testing splits cleanly into two problems. Proximate analysis is high-volume and routine — Kjeldahl nitrogen, Soxhlet fat, ash, moisture — and cost per test matters. Residue and contaminant analysis is the opposite: low volume, high stakes, and entirely dependent on solvent and standard quality, because the specification is about what is absent. Pesticide-residue grade solvents exist for exactly this reason and are not interchangeable with AR grade.
Tests run here
- Crude protein by Kjeldahl
- Crude fat by Soxhlet extraction
- Moisture, ash and crude fibre
- Pesticide residues by GC-MS and LC-MS/MS
- Heavy metals by AAS
- Aflatoxin and mycotoxin screening
- Microbiological plate counts and pathogen detection
