The Benefits of the Geno/Grinder® High-Throughput Tissue Homogenizer to Increase Sample Throughput for Pesticide Residue Analysis by LC/MS/MS
15 May 2013The high-throughput analysis of pesticides has been hindered by slow and laborious sample preparation. This application note evaluates a new approach using an innovative laboratory tissue homogenizer to extract various pesticide residues from different kinds of plant materials and to identify and quantify active ingredients by LC/MS/MS.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.Sample HomogenizerPesticidesPesticides are used to protect crops from diseases, pests and unwanted plants. They are classed as persistent organic pollutants (POPs) and can be harmful to humans. The Environmental Protection Agency (EPA) currently regulates the use of pesticides in the USA.
