Food & Agriculture Sample Preparation

Strawberries, soybeans and apples diced, homogenized and analyzed by GC-MS. When combined with the QuEChERs pesticide extraction method, high recoveries can be achieved from a variety of produce types.

This application note describes a general approach for the clean-up of a non-polar solvent extract of vegetable material.

This application brief describes Quechers extraction of a representative panel of 50 pesticides, incorporating pesticides, fungicides and insecticides from spinach samples. 

This method describes the clean-up of acrylamide from cooked foodstuffs, using a multimode retention mechanism (hydrophobic, cation and anion exchange) for retention of interfering food components.

Melamine is traditionally used in making plastics, however, it’s low cost and high nitrogen content has led to exploitation in various sections of the food industry, most notably involving dairy products. Sometimes used as an adulterant to increase apparent protein content in milk products such as infant formula, melamine is toxic, and can cause renal failure.
