Clean, usable water that’s free of harmful pollutants is critical to everyday life. Analyzing water for perfluorinated compounds (PFAs), nitrosamines, or other volatile compounds or chemicals can be a time-consuming process that’s streamlined through automation. Water analysis typically lays the groundwork for studies on quality, pollution, hydrology, and more. At Gilson, we have various products and automated solutions to help your water analysis workflows.
Automated Solid Phase Extraction (SPE) of 10 Perfluorinated Compounds (PFAs) from Tap Water
Perfluorinated compounds (PFAs) 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 before their analysis by LC/MS.
Large Volume ASPEC® 274: Determination of Nitrosamines in Drinking Water
Nitrosamines are a class of semi-volatile organic chemical compounds characterized by a nitroso group attached to an amine group. In this tech note, we describe a method for automating US EPA Method 521 using the Gilson ASPEC® 274 Large Volume System.
This ASPEC system maximizes throughput for small- to large-volume solid phase extraction (SPE) applications by processing four samples in parallel with positive pressure elution. With its small footprint, multiple probes, and out-of-bed sample processing, it is the ideal choice for high-throughput SPE automation for the isolation of trace contaminants in water. Combined with ASPEC SPE Cartridges, it generates reproducible and efficient sample cleanup for environmental testing and research labs.
The cost-effective, pre-capped ASPEC® Solid Phase Extraction (SPE) cartridges tackle most separation challenges and are ready to use on any ASPEC System. Each phase allows low solvent consumption and reliable analysis with reproducible separation, high loading capacity, and accurate elution properties.
This ASPEC® system provides ultimate workflow automation of small- to large-volume solid phase extraction (SPE) applications by combining flexible positive pressure SPE, precise liquid handling, large bed capacity, With a single probe, this system is ideal for lower-throughput applications and is highly flexible allowing you to automate other sample preparation techniques such as liquid-liquid extraction (LLE).
