Pesticide Residues | Clean up / Determine / Analyze pesticide residues with our full product line.

Low levels of pesticides are present in harvested crops to improve yields and to protect from insect infestation, weeds, and plant diseases. Pesticide usage is strictly regulated in many countries. Maximum Residue Limits (MRL’s) are established to protect consumers from the harmful health effects of overexposure.

Prior to analytical determination, solid phase extraction (SPE) of pesticide residues in food is achieved with Multi-Layer SPE tubes, QuEChERS (Dispersive SPE), solid phase microextraction (SPME) or by liquid-liquid extraction (LLE)

Pesticide residues are found not only in food sources such as plant or animal tissues and animal feed, but also in the Pesticide Fate Process, through:
