Description générale

Squalene is a naturally occurring triterpenoid and a precursor to sterol biosynthesis. Typically isolated from shark liver, olive, amaranth, and algal oils, it shows various cosmetic and medicinal uses.

Application

This analytical standard can also be used as follows:

  • Analysis of 119 vegetable oil samples from 7 different varieties to detect and determine squalene and four sterols using a developed and validated non-destructive method based on proton nuclear magnetic resonance (1H NMR) spectroscopy combined with partial least squares (PLS) method
  • Determination of squalene in different oil samples by gas chromatography coupled to flame ionization detection (GC-FID) following base-catalyzed transmethylation of the oil base
  • Ultra-high performance liquid chromatography-photodiode array detection (UHPLC-PDA) based quantification of squalene, following its single-step solid phase extraction (SPE) from 33 samples of extra virgin olive oil collected from different countries
  • Measurement of squalene content of 16 commercial shark liver oil samples using a gas chromatography-mass spectrometry-based method, in addition to IR and Raman spectroscopy combined with the PLS method
  • Multi-residue determination of 14 naturally occurring compounds— squalene, tocopherols, and phytosterols, following their solid phase extraction (SPE) from 15 vegetable oil samples by GC-MS

Questions

1–2 sur 2 questions  
  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 réponse
    1. 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

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

    1 réponse
    1. 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.
