General description

For Gases and Low Molecular Weight Compounds (MW 30-225)
We are committed to bringing you greener alternative products, which adhere to one or more of The 12 Principles of Greener Chemistry. This is a Solid Phase Microextraction (SPME) technology product. SPME is one of the greener technologies for sample preparation as it is solvent free extraction technology and SPME fibres are re-usable and generates as little waste as possible, thus aligns with "Waste Prevention”, and ″Safer Solvents and Auxiliaries″. Click here for more information.

Footnote

This SPME fiber assembly is also available with a Nitinol (NIT) core as Cat. No. 57901-U, providing enhanced fiber reproducibility, greater fiber durability, maintained selectivity for method consistency, and core inertness to ensure analyte stability. See more at SigmaAldrich.com/NITSPME .

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What types of compounds would be suitable for extraction using SPME fiber assembly Carboxen/Polydimethylsiloxane(CAR/PDMS), Product 57344-U?

    This fiber is best suited for extracting relatively small volatile compounds.  The approximate size range of the compounds is between 2-10 carbons, and should be suitable for most functional groups (i.e., alcohols, acids, mercaptans, etc).

  4. Is SPME fiber assembly Carboxen/Polydimethylsiloxane(CAR/PDMS), Product 57344-U, also available with the new metal core technology?

    Yes, this fiber is available with a fused silica, Stableflex, or metal fiber cores.  The metal fiber assemblies are only available in 23 gauge needles, and should be used with a Merlin Microseal on the GC injection port

  5. How do I find price and availability?
