兽医消毒剂的稳定性因温度和时间而异. 大多数药物在21天内保持90%以上的疗效,但有些药物在较高的温度下会更快地降解,建议每天做好准备或仔细储存.
科学领域:
- 兽医医学 兽医医学 兽医医学
- 分析化学是一种分析化学.
- 生物安全是生物安全.
背景情况:
- 兽医消毒剂的有效期对于预防疫情期间的消毒和生物安全故障至关重要.
- 由于缺乏关于稀释消毒剂储存条件的既定标准,因此需要对其稳定性进行调查.
- 了解储存条件对消毒剂有效性的影响,对于有效控制动物群的疾病至关重要.
研究的目的:
- 检查稀释兽用消毒剂中活性成分的化学稳定性.
- 为了确定各种储存温度和时间段对消毒剂度的影响.
- 提供数据,以确定稀释的兽医消毒剂溶液的适当储存条件.
主要方法:
- 选择了20种针对口病或禽流感病毒有效的兽医消毒剂.
- 将消毒剂稀释到制造商指定的度,并将其存储在4,20,30和45°C,持续时间不同.
- 使用选择性分析技术量化活性成分度,包括对两个样本的冷/解周期后的稳定性测试.
主要成果:
- 大多数活性成分在测试条件下在21天内保持≥90%的初始度.
- 葡萄糖甲,甲和酸在21天后在45°C下显示稳定性降低 (<90%).
- 过氧化和酸度随着时间和温度的增加而迅速下降.
结论:
- 建议每天制备稀释消毒剂溶液,以获得最佳的疗效.
- 该研究提供了关于常见兽医消毒剂的化学稳定性的重要科学数据.
- 结果可以指导选择合适的储存条件,当每日准备是不可行的.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
