    • A process for the co-precipitation of a substance with a stabiliser therefor, by a gas anti solvent process comprising introducing into a particle formation vessel a supercritical fluid pure or mixed with a modifier; and a solution comprising said substance and said stabiliser dissolved in a solvent; so as said solvent is extracted from the solution by said supercritical fluid and co-precipitation of the substance and stabiliser occurs. The process may be carried out using an apparatus comprising a particle formation vessel (22) and a nozzle (27) having a central orifice (39) serving to introduce a solution of the substance and a plurality of outer orifices (41) serving to carry a flow of supercritical fluid into the particle formation vessel (22), such that the solvent is extracted from the solution by the supercritical fluid and precipitation of micron sized particles of the substance/stabilizer occurs. The substance is preferably a protein of pharmaceutical interest, which is highly stabilized for storage by this process.
    • 一种通过气体反溶剂方法使物质与稳定剂共沉淀的方法,该方法包括向颗粒形成容器中引入纯净的或与改性剂混合的超临界流体; 以及包含溶解在溶剂中的所述物质和所述稳定剂的溶液; 从而通过所述超临界流体从溶液中提取所述溶剂并且发生物质和稳定剂的共沉淀。 该过程可以使用包括颗粒形成容器(22)和喷嘴(27)的装置来实施,所述喷嘴具有用于引入所述物质的溶液的中心孔口(39)和用于承载所述物质的多个外部孔口(41) 超临界流体流入颗粒形成容器(22)中,使得通过超临界流体从溶液中提取溶剂并且发生物质/稳定剂的微米尺寸颗粒的沉淀。 该物质优选是药物感兴趣的蛋白质,其通过该过程高度稳定以用于储存。
