As we find new ways to grow food, clean our water supply, and identify new pathogens, it is increasingly important to make sure your application is accurate and optimized to ensure quality, nutritious food and a safe environment for us to live in. For example, analysis is performed at all stages of food production, including the intake of raw materials, food processing, and final product packaging, and there are many different analytical techniques that can be used.
From analyzing pesticides on crops to identifying perfluorinated compounds (PFCs) in water, your food safety and environmental applications can benefit from Gilson’s range of extraction and liquid handling solutions.
Per- and poly-fluoroalkyl substances (PFAs), sometimes referred to as perfluorinated compounds, are a family of molecules consisting of varying lengths of fluorocarbon chains with a functional group such as carboxylic or sulfonic acid attached. This application note describes the automation of the isolation of 10 PFAs from tap water prior to their analysis by LC/MS.
In food safety, sample matrices are commonly very complex and usually require the regulation of multi-residue compounds. Automating protocols with liquid handlers provides repeatability and gives you greater confidence in your results. Here's a quick overview of automated SPE for your food safety workflows.
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 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 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.
