General description

Oleic acid is a long-chain unsaturated fatty acid, having a double bond between C9 and C10 with a cis configuration. It is the most found fatty acid and occurs in most oils and fats to some extent.
This substance is listed on the positive list of the EU regulation 10/2011 for plastics intended to come into contact with food. Find all available reference materials for compounds listed in 10/2011 here

Application

This analytical standard can also be used as follows:

  • Simultaneous identification and quantification of fatty acids from blood plasma samples after their methyl derivatization by large-volume injection (LVI) gas chromatography combined with vacuum ultraviolet spectroscopy (GC-VUV)
  • Determination of the fatty acid composition of sunflower seed oils extracted from 93 different sunflower varieties by near-infrared reflectance spectroscopy (NIRS) combined with modified partial least squares (MPLS) and partial least squares (PLS) regression methods
  • Separation and quantification of palmitic, oleic, linoleic, and linolenic acids from 186 samples of sea buckthorn seed oil using near-infrared spectroscopy (NIR) in combination with four different combinations of multivariate calibration methods— partial least squares (PLS), PLS-uninformative variables elimination (UVE), PLS- competitive adaptive reweighted sampling (CARS), and multiple linear regression (MLR)-UVE
  • Multi-residue analysis of oleic acid and other related fatty acids using a derivatization-free method based on gas chromatography-flame ionization detection (GC-FID)
  • Ultra-performance liquid chromatography-mass spectrometry (UHPLC) method-based separation, identification, and determination of eight saturated and unsaturated fatty acids in eight different commercial samples of olive oil without any prior sample treatment
  • Development of a liquid chromatography-mass spectrometry (LC-MS) method to measure seven fatty acid esters of hydroxy fatty acids (FAHFAs), four fatty acids, and four cardiovascular-related biomarkers in plasma samples of 57 healthy individuals

Questions

1–2 of 2 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

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

    1 answer
    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
