Food & Agriculture
Heavy metals, pesticide residues, authenticity and contaminants.
The workflow
Food testing covers an unusually wide matrix range — from rice and seafood to oils, spices and feed — and each matrix brings its own digestion or extraction problem.
LabTech's catalog is built around those differences: single-chamber digestion that takes food, soil and plastics in the same batch, GPC and SPE cleanup for pesticide residues, and isotope ratio mass spectrometry for authenticity and origin work.
What makes it difficult
- Complete digestion of fat- and carbohydrate-rich matrices without loss of volatile elements
- Removing matrix before GC-MS/MS analysis of pesticide residues
- Confirming geographical origin and adulteration claims
- Keeping reagent blanks low enough for trace-level work
