粉碎問題
|
| 我正在做一個(gè)藥,不粉碎達(dá)不到我想要的粒度而導(dǎo)致溶出不好,粉碎就會(huì)有雜質(zhì)增大,且穩(wěn)定性不好(粉碎后比不粉碎的原料雜質(zhì)增加快且大)?該怎么辦?為什么呢?破壞單晶了?可是一定要粉碎。亢铣晒に嚿、結(jié)晶步奏上.....能解決嗎? |

For your reference: It’s better to ask your analytical group to help you. 1) Try force degradation by different temperature to understand if your impurity is from heat. Find the suitable temperature range for your 原料粉碎. 2) Add 1-5% water into your 原料, test impurity at different time points to understand if there is any hydrolysis from your原料. 3) Identify your impurity and understand what really happened during原料粉碎 and re-design your process to get ideal particle size. |
