一般說明

Aflatoxins are a group of hypertoxic secondary metabolites produced by fungi of the genus Aspergillus, mostly A. flavus, A. Parasiticus, and A. nomius. Of the 20 aflatoxins identified so far, B1, B2, G1, and G2 are the four naturally occurring aflatoxins.

應用

It is intended to be used for the calibration of analytical instruments, validation of analytical methods, determination of detection limits and linearity studies, and recovery experiments.

This aflatoxin mix 4 solution was used as follows:
  • Ultra-high-performance liquid chromatography-fluorescence detection (UHPLC-FLD) based quantification of aflatoxins— B1, B2, G1, and G2, in the coffee bean and powder samples
  • Estimation of aflatoxins (B1, B2, G1, and G2) in samples of maize, rice, sorghum meal, and peanuts by ultra high-performance liquid chromatography coupled with a fluorescence detector
  • Determination of naturally occurring aflatoxins in 65 peanut-enriched flour samples by high-performance liquid chromatography (HPLC) combined with fluorescence detection

成分

B1、G1、B2、G2 的乙腈溶液(各 20ug/mL)

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
