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.

General description
Application
- Construction of a multi-bed needle-trap device for sample treatment of volatile organic compounds in indoor air samples collected from an office, corridor, and a laboratory, for their analysis by gas chromatography-flame ionization detector (GC-FID)
- Development of a Carbotrap B sorbent-packed needle-trap device for the sampling of benzene, toluene, ethylbenzene, and xylene isomers from air samples for their analysis by gas chromatography-mass spectrometry (GC-MS)
- Simultaneous detection and quantification of 14 volatile organic compounds (VOCs) from 283 flavored refill liquids, 21 nicotine refill liquids, and 12 cartridges of electronic cigarettes by headspace solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS)
- GC-MS detection of 11 VOCs following their extraction using a dynamic headspace needle-trap device (D-HS-NTD) having ZIF-8-derived nanoporous carbon (ZIF-8-NPC) as an adsorbent, from 20 pen ink samples
- Determination of seven volatile organic compounds in the surgically resected colonic tissue samples of colorectal cancer patients by gas chromatography-mass spectrometry (GC-MS) following their extraction by headspace- and direct injection- based solid phase microextraction (SPME)

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