CHROMABOND® QuEChERS mixes with special diamino silica phase are suitable for determination of pesticides in food samples. These remove polar compounds (organic acids, pigments, sugars) from matrices like fruit or vegetables.
- Quick, Easy, Cheap, Effective, Rugged, Safe
- Multi-residue pesticide analysis of fruits or vegetables
- Pre-weighed CHROMABOND® QuEChERS mixes
For subsequent clean-up, a diamino phase (PSA) removes sugars and organic acids. Magnesium sulphate removes water, C18 ec removes nonpolar interferences such as fats and the carbon phase removes pigments, sterols, and nonpolar interferences.
