一般說明

碳酸钠通常被称为苏打粉。索尔末法用氯化钠和石灰石生产碳酸钠。[1]碳酸钠提高了稻草的预处理并提高了脱木素工艺。[2]碳酸钠在提取生物活性代谢物中得到应用,如环氧二萜和生物碱,并从萃取物中去除酸性化合物。[3]在盐诱导相分离萃取法(SIPSE)中,碳酸钠诱导相分离,提高了乙腈对等离子体的分配。[4]

應用

碳酸钠已可用于:
  • 利用 榄仁树 提取物抑制α-葡萄糖苷酶活性[5]
  • 作为酶联免疫吸附试验(ELISA)的碳酸氢盐/碳酸氢盐缓冲液的成分[6]
  • 作为 共生孢子 生长培养基中的一种成分[7]

Questions

1–4 of 4 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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf
