General description
Supelpak™-2 is purified Amberlite™ XAD®-2 that has been cleaned to meet and exceed US EPA-recommended criteria for purity, as outlined in Level I Environmental Assessment Procedures Manual. It is the best resin to use for standard air sampling methods requiring resin tested for background TCO (total chromatographic organics) level. Packaged in glass containers.
We are committed to bringing you Greener Alternative Products. This product is a Design for Sustainability (DfS) developed product, which belongs to one of the four categories of greener alternatives. Click here to view its DfS scorecard.
Application
Supelpak-2 was used as adsorbent in an extraction procedure and the extracts were analysed using GC-MS, GC-FTIR, Proton NMR and GC-NPD

A method to sample and analyze chlorothalonil and dichlofluanid in greenhouse air was evaluated. Analysis was performed by gas chromatography with electron capture detection and gas chromatography-mass spectrometry. Solid sorbents such as Chromosorb 102, Porapak R, Supelpak-2, Amberlite XAD-2, Amberlite

Male American palm weevils (APWs),Rhynchophorus palmarum (L.) produced two sex-specific compounds, which were disclosed by volatile collections on Supelpak-2 and gas chromatography. One was a minor compound, not always detected. The major male-produced volatile was identified as (2E)-6-methyl-2-hepten-4-ol through coupled
