Traditional techniques used to perform the extraction of pesticides from food matrices are time consuming, solvent intensive and can deliver inconsistent results. The need for economical, fast, reproducible testing protocols exists. Perform consistent extraction of pesticides for analytical quantitation in 10 minutes. The PLE can dramatically improve reproduciblity of results, speed and cost of extractions.

Internal standards (IS) are commonly incorporated into quantitative methods to increase accuracy and precision. An IS is a compound that is different than the analyte of interest, has similar physicochemical properties to the analyte, and is added to samples, calibration standards, and quality control samples in a known quantity. It should not be present in the sample, it should be available in high purity, and it should be easily differentiable from the analyte of interest. Read more
