Pesticides are substances designed to control pests, including those that spread human or animal diseases, unwanted species of plants or animals, or any organism that could cause harm during the production, processing, or storage of food and agricultural commodities. The most common pesticides are intended to serve as plant protection products for farmers or agricultural manufacturers but can be harmful if consumed in large quantities. Read on to learn about pesticide analysis and how our products and services can help your workflows.
Are Your Products Free of Pesticides?
While pesticides protect crops during the growing and production stages, these chemicals must be eliminated from products to ensure they are safe for commercial consumption. Most foods or natural samples are complex; therefore, sample preparation is most often required before the analysis to achieve reliable analytical results. Solid phase extraction (SPE) is the most selective isolation/cleanup technique to reduce matrix effects during the analysis and guarantees accurate and reproducible analytical results.
LC-MS/MS Detection of Glyphosate/AMPA/ Glufosinate in Red Wine Without Prior Derivatization
Since 1970, glyphosate has been used as a systemic, non-selective herbicide and crop desiccant on farms, in fields, and in public and residential areas. This application note describes the automation of the isolation of glyphosate, aminomethylphosphonic acid (AMPA), and glufosinate from red wine using a Gilson ASPEC system.
This ASPEC® system for positive pressure solid phase extraction (SPE) maximizes throughput by processing up to four samples in parallel. With its small footprint and multiple probes, it is the ideal choice for high-throughput SPE automation on 1, 3, or 6 mL cartridges. Combined with ASPEC SPE Cartridges, it generates reproducible and efficient sample cleanup for clinical, forensic, doping, food, and environmental testing labs.
This ASPEC 271 System provides the ultimate versatility by combining flexible, positive pressure solid phase extraction (SPE), precise liquid handling, large bed capacity, and on-line integration with liquid chromatography (LC) systems. With its large cartridge capacity and small footprint, it enables unattended processing of a high number of samples per day for any SPE application, even those requiring multiple cartridge extractions.
This compact ASPEC® system combines positive pressure solid phase extraction (SPE) with precise liquid handling for reliable automated SPE applications. Its minimized footprint makes it the ideal choice for basic SPE automation when bench space or throughput is limited. The dual syringe pump option allows for automated internal standard addition. Combined with ASPEC SPE Cartridges, the system generates reproducible sample cleanup for clinical, forensic, doping, food, and environmental research labs.
With a uniform and consistent flow rate, the ASPEC Positive Pressure Manifold improves solid phase extraction (SPE) reproducibility and recovery, even with high viscosity samples. The manifold offers better control among samples and between runs than traditional vacuum manifolds, providing greater confidence in your data. It’s easy to set up and use, so you can start immediately.
