一般描述

这种聚苯乙烯基微粒（粒径：0.1 μm）粒径标准是描述测试样品粒径分布(PSD)特征的理想之选。

应用

用于校准、鉴定和监测精度分析仪、表面扫描仪和粒子计数器的性能。
单分散聚苯乙烯乳胶颗粒也可用于：
  • 研究其对淡水藻类的影响[1]
  • 研究三苯基锡(TPT)的毒性对海洋浮游硅藻的影响[2]
  • 显示他们与蓝藻细菌在海洋和淡水环境中的相互作用[3]

特点和优势

  • 适用于日常仪器的校准检验、测试和校正
  • 以5 mL和10 mL包装规格的洁净样品形式提供

分析说明

对于每个批次，测定粒度和标准偏差的精确值的准确度为 0.001μm。这些颗粒的粒度测定分别遵循美国国家标准与技术研究所 (NIST, USA) 和欧盟参考局 (BCR) 描述的程序，尤其是：
  • 透射电子显微镜（TEM）
  • 扫描电子显微镜
  • 光学显微镜
  • Coulter™ 计数器，带MDF系统
采用NIST-respectively BCR粒度标准物质进行设备校准。

Questions

1–5 of 5 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

  3. What is the composition/information on the ingredients of the aqueous suspension?

    1 answer

    1. The complete composition of this product is considered proprietary. However, this aqueous dispersion is stabilized by the addition of an anionic surfactant.

  4. If I would like dilute the concentration of this solution what solvent can I dilute it with?

    1 answer

    1. Product 90517 can be further diluted in water with added sodium dodecyl sulfate to prevent aggregation.

      Helpful?

  5. What will be the amount of polystyrene in milligrams of 5 ml of .1 micrometer polystyrene solution

    1 answer

    1. This product is prepared as a 2 % suspension (2 g/100mL) of 0.1 µm polystyrene particles. The 5 mL package size will contain approximately 100 mg of the polystyrene particles.
