一般描述

氨溶液（溶于甲醇的氨）是一种无色气体，具有特征性强烈气味。它极易溶于水、醇、氯仿、醚、乙醇和甲醇。氨溶液通常被用作碱。

应用


  • 综合方法揭示左金丸对慢性萎缩性胃炎大鼠模型胃粘膜损伤的治疗机制。：本研究在实验装置中使用氨溶液探讨了左金丸的多方面药理作用，这有助于了解其对胃粘膜损伤的保护机制（Chen L et al., 2024）。

  • 以电镀污泥为锌源合成磷酸锌铵的研究。：本研究专注于可持续实践，采用氨溶液从工业废料中合成磷酸锌铵，提出了一种回收利用和环境保护的新方法（Morgovan CM et al., 2024）

  • 了解锌离子在感染性尿路结石情况下对鸟粪石成核和生长的作用。：这项冶金研究探讨了氨溶液如何与锌离子相互作用而影响鸟粪石晶体的形成，这对于阐释尿路感染的病理过程至关重要（Prywer J et al., 2024）。

  • 使用离子液体基双水相系统从LiFePO4电池正极材料中回收金属。：将氨溶液用于创新的离子液体系统，从废旧电池中回收有价值的金属，有助于可持续性材料管理（Li X et al., 2024）。

  • 高效且可重复的ZnO纳米晶体声化学合成。：这项研究展示了氨溶液在ZnO纳米晶体声化学合成中的应用，提出了一种生产高质量纳米材料的可重复方法（Fioravanti A et al., 2024）。

Recent studies suggest that alkalinizing treatments improve the course of chronic kidney disease (CKD), even in patients without overt metabolic acidosis. Here, we tested whether a decreased ability in excreting urinary acid rather than overt metabolic acidosis may be deleterious

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.

  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
