Dear Customer:

The current international situation is complex and volatile, and uncertain tariff policies may potentially impact our product prices. Given these uncertainties, we value your understanding regarding order-related matters.

If you decide to place an order during this period, we reserve the right to adjust the price based on the evolving situation. We understand that market changes may cause inconvenience. We will negotiate with you if there’s a significant price fluctuation due to tariff policy changes before the order’s actual delivery, and in such cases we may adjust or cancel the order as necessary.

应用


  • 食品和环境基质中痕量金属的同时伏安法测定分析程序。与原子吸收光谱法测量的关键比较。：本文介绍了一种使用柠檬酸氢铵同时对食品和环境样品中的痕量金属进行伏安法测定的分析程序。该研究表明，与传统原子吸收光谱法相比，该方法是有效的（Melucci et al., 2007）。

  • 重叠伏安峰——一种同时测定痕量金属的分析程序。应用于食品和环境基质。：该研究详细介绍了一种使用柠檬酸氢铵解析重叠伏安峰的分析方法，可以同时测定复杂基质中的多种痕量金属。该技术有助于环境监测和食品安全评估（Locatelli, 2005）。

  • 饲料磷酸盐的生物学价值与其在水、稀氯化氢、稀柠檬酸和中性柠檬酸铵中的溶解度的相关性研究。：本研究考察了饲料磷酸盐在柠檬酸氢铵等各种溶剂中的溶解度，以确定其生物学价值。这些发现有助于优化动物饲料配方，以获得更好的营养结果（Sullivan et al., 1992）。

    Chimeric oligonucleotides containing phosphodiester and phosphorothioate linkages have been obtained using the solid phase synthesis. The oligonucleotide parts possessing natural internucleotide phosphate bonds were assembled using commercially available nucleoside 3'-O-(2-cyanoethyl-N,N-diisopropylamino)phosphoramidites 7 whereas the phosphorothioate segment was built using nucleoside 3'-O-(2-thio-1,3,2-oxathiaphospholanes)
