Poly(ethylene Glycol) is used in various applications from industrial chemistry to biological chemistry. Recent research has shown PEG maintains the ability to aid the spinal cord injury recovery process, helping the nerve impulse conduction process in animals. In rats, it has been shown to aid in the repair of severed sciatic axons, helping with nerve damage recovery. It is industrially produced as a lubricating substance for various surfaces to reduce friction. PEG is also used in the preparation of vesicle transport systems in with application towards diagnostic procedures or drug delivery methods. 物质的分类: 1. 按来源: (1)25322-68-3Poly(ethylene Glycol) ~20000国际化学标准物质(WHO) (2)美国药典标准物质(USPC,USP) (3)欧式药典标准物质(EDQM,EP) (4)日本药局标准物(PMRJ,JP) (5)国家药品标准物质(NICPBP,CHP) 2.按测定方法和使用对象: (1)生物标准物质 (2)化学标准物质(化学对照物质) 3.按使用要求: (1)国际化学对照品 (2)国家化学对照品 (3)工作化学对照品 4.按用途: (1)鉴别用化学对照品 (2)纯度或杂质检查用对照品 (3)含量测定用对照品 (4)标准仪器用对照品 5.按药品使用对象: (1)化学对照品 (2)中药化学对照品 (3)抗生素化学对照品 (4)麻醉药品化学对照品 对照品的化学定量分析方法与流程:
