Application

SPME fiber assembly Divinylbenzene/Carboxen/Polydimethylsiloxane (DVB/CAR/PDMS) is used for the analysis of VOC emissions from historic plastic and rubber materials using headspace-solid phase microextraction with gas chromatography coupled with mass spectrometry.[1]

Features and Benefits

Designed for use with Merlin Microseal sealing system; can be used with other septumless systems.

General description

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.

Other Notes

Appearance may vary. Darker spots may be visible on the fiber but will not affect performance.

Coating bonded to a flexible fused silica core, yielding a more suitable coating on a less breakable fiber. There may be a slight difference in extraction selectivity compared to the same coating on a standard fused silica core.

How can I determine the shelf life / expiration / retest date of this product?

1 answer

  If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
  For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
  For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

How is shipping temperature determined? And how is it related to the product storage temperature?

1 answer
1. Technical Support
  
  10 months ago
  
  Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

Which gauge is larger, 23 or 24?

1 answer
1. Technical Support
  
  2 years ago
  
  The gauge designation and actual size of needles follow an inverse relationship. Therefore, a 24 gauge needle is smaller than a 23 gauge needle. Needle gauge sizes also apply to the SPME needle used for sampling. While the original SPME fibers were manufactured with 24 gauge needles, it is highly recommended to use 23 gauge needles for all applications that involve an autosampler. The 23 gauge needles are well-suited for use with the Merlin Microseal septum system and other septum-less seals. However, it is advisable to avoid using 23 gauge needles with standard silicone septa, as they may cause coring of the septum.
