Analysis of highly polar pesticides

CTC Analytics AG
17 Apr 2024

Micro-SPE (μSPE) has emerged as an automated green micromethod for sample preparation and clean-up in various fields such as food safety, proteomics, forensics, and environmental analysis for over a decade. The automation of μSPE sample preparation steps has standardized sorbent materials for extract clean-up across different food commodities, increased sample throughput, and provided potential for offline and online hyphenation with GC-MS, LC-MS, or even IC analysis.

CTC Analytics details the analysis of eleven highly polar pesticides (HPPs), including glyphosate, glufosinate, ethephon, and fosetyl-aluminium, along with their related metabolites, from complex food matrices such as honey and pollen. For the first time, micro-SPE clean-up is introduced for HPPs to address known analytical limitations by removing polar co-extracts through automated clean-up processing of sample extracts.

PAL µSPE

CTC Analytics AG

The PAL µSPE cartridge stands for a miniaturized and robust SPE technology that allows reliable automation and reduction of used sample and solvent without compromising performance. The µSPE has therefore emerged as a new standard for extraction, purification, concentration or filtration for automated environmentally friendly analysis processes.

LC-MSLC-MS (liquid chromatography-mass spectrometry) systems and equipment are used for separation and quantitative analysis of complex mixtures, combining liquid chromatography and mass spectrometry. Quantify proteins, contaminants, pesticides or screen for drug metabolites with a high level of sensitivity. LC-MS systems and equipment include reverse phase, normal phase and specialized columns integrated with various MS detectors such as time-of-flight (TOF), quadrupole, orbitrap or ion trap mass analyzers. LC-MS/MS instruments equipped with a qTOF or triple quadrupole analyzer give greater sensitivity and resolving power to your analysis. Find the best LC-MS equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.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.PesticidesPesticides 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. Food SafetyFood safety describes the prevention of food-borne illnesses. Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.Environmental AnalysisEnvironmental analysis describes a variety of tests that determine the effect of chemicals, processes and particulates such as persistent organic pollutants (POPs) have on the environment.
