Discover Food Safety and Quality
Pesticides contaminate many foods – especially fruits and vegetables – during the growing season through soil, water, and air indirectly or directly. With residual levels regulated for human health and safety, short analytical turnaround times are critical to providing the necessary information required to make rapid decisions about food, safely. For rapid screening of food matrices to detect the presence of pesticides residues, our chromatographic technologies are trusted throughout the industry.
Pesticides are employed in the growing of crops to prevent damage from a number of pests and fungi. When crops are grown to produce feed for livestock, there is a potential for pesticides residues to remain on the feeding stuffs, posing a risk to the livestock ingesting them. Pesticide residues are regulated by a number of governmental agencies, necessitating analytical methods that are robust enough to analyze complex matrices for a variety of analytes, while also being sensitive and selective enough to meet stringent regulations. In this application note, a fast, sensitive, and selective multi-residue method has been developed for the analysis of 94 pesticides in animal feeding stuffs, with reporting limits below European Commission MRLs of 0.01 mg/kg.
Pesticides can adversely affect human health through the food we consume but can also leach into soil and groundwater and impact us through the environment. To keep up with a complex and constantly changing regulatory environment, your pesticide analysis solution needs to keep up with your burgeoning sample load.
Both pesticides and illegal additives, if present in significant levels in wine, can pose health risk to consumers. In this study, a simple and sensitive LC-MS/MS method has been developed and applied for the determination of both pesticides and pigments in a single analytical run.
Liquid chromatography tandem mass spectrometry (LC/MS/MS) has become the method of choice for pesticide analysis due to its high selectivity and sensitivity as well as its suitability for a wide range of compounds in various sample matrices. 0 In this study, a fast, sensitive and selective multi- residue method has been developed for analysis of over 200 pesticides in rice samples by coupling a modified QuEChERS extraction method with LC/MS/MS. Using time-managed- MRM™ in the QSight® triple quadrupole mass spectrometer, the optimum dwell time of multiple MRM transitions can be generated automatically for the targeted analytes. This not only saves time in method development but also improves data quality and analytical performance, as demonstrated in this study by the results of multi- residue pesticide analysis in rice samples.
