New, Improved, Online Solid Phase Extraction Method Development Tool Now Brings You Even Greater Functionality

Developed by Anachem’s chemists, with over 15 years SPE and HPLC expertise the SPE Online Method Development Tool at www.spenet.co.uk is a FREE web based SPE method development tool that has just been significantly improved to give you even greater functionaility. SPEnet allows you to specify any number of compounds to extract, what interferences to remove, and select your desired sample matrix. The web site then provides you with estimates of logP and pKa values, chromatographic retention estimates – even for new chemical entities – and a recommended SPE method.

The website has a built-in structure drawing tool, allowing users to input new chemical entities. A recent improvement to the site is the addition of lists of pre-drawn structures (including many pesticides, herbicides, priority pollutants, and pharmaceuticals) for faster data entry. Another major change is a significant improvement in the algorithms used by SPEnet to estimate logP & pKa/pKb values and the algorithms used to predict SPE methods. Finally, www.spenet.co.uk displays calculated pKa and logP values for the structures drawn, significantly improving the amount of information the website provides.

To assist you further in developing your SPE and HPLC methods, our chemists have developed the site to give a quick graphical representation of reverse phase chromatographic retention values versus the pH range. With predictions of chromatographic behaviour vs. pH, charge vs. pH relationship, logP and pKa values all given for free, www.spenet.co.uk provides the best free online method development resource for analytical chemists involved in SPE or HPLC method development.

SPEnet suggested methods are best starting points for the extraction you want to perform. The methods are based on Anachem’s new SPEnet range of solid phase extraction cartridges, 96-well SPE plates and SPE method Development Kits. You can source all these top quality SPE consumables at www.labstore.co.uk and order directly online, saving time and money.

Anachem provides the complete solution for SPE consumables, protocols, automation method development and technical support. We support automation of solid phase extraction, protein precipitation, and liquid-liquid extraction methods utilizing the Gilson ASPEC Xli or XL4 (automated SPE) or any Gilson liquid handler.
