一般描述

应用：这种非极性通用色谱柱主要使得组份按照沸点高低顺序洗脱，选择性略有提高，特别适用于芳香族化合物。
USP 代码：本色谱柱符合 USP G27 和 G36 要求。
相：
  • 结合的
  • 聚（5％ 二苯基/ 95％ 二甲基硅氧烷）
温度限制：
  • ≤0.32mm 内径，<2 μm：-60°C 至 320°C（等温或程序化）
  • ≤0.32mm 内径，<2 μm：-60°C 至 300°C（等温或程序化）
  • ≥0.53mm 内径，<2 μm：-60°C 至 300°C（等温）或 320°C（程序化）
  • ≥0.53mm 内径，<2 μm：-60°C 至 260°C（等温）或 280°C（程序化）

应用

SPB®-5 毛细管 GC 柱用于通过化学发光法检测氮化合物（定量）的形态，其是极性的，本质上是碱性的。[1]它也可以用作固定相，用于通过电子捕获气相色谱法测定谷物中的雪腐镰刀菌醇和脱氧雪腐镰刀菌醇。[2]此外，它还可作为固定相，用于毛细管柱气相色谱法测定甾醇。[3]

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.
      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
