【正文】 ges. Materials that inhibit microbiological growth should not be used. If a test material is utilized, a further decision between a liquid or powder material is also required. Those firms that have chosen to segment the process simulation according to the various unit operations may elect to make different selections for the test material in different parts of their overall program. For example, in sterile BPC simulations with a crystallization step, a liquid material may be used during simulation of the early steps, and a powder material in those steps which follow the crystallization step. 不管決定是模擬整個(gè)無(wú)菌工藝或部分單元操作的形式，應(yīng)考慮模擬使用的物料的選擇。選擇是：促進(jìn)微生物生長(zhǎng)的培養(yǎng)基，安慰劑物料，無(wú)物料模擬或?qū)嶋H產(chǎn)品物料 （通常為輔料）。每種選擇都有一定的優(yōu)點(diǎn)和缺點(diǎn)。不能使用抑制微生物生長(zhǎng)的物料。如果選擇了一種測(cè)試物料，進(jìn)一步需要決定選擇液體或粉末物料。那些決定按照不同的單元操作將工藝模擬分開(kāi)的公司，可能需要在整個(gè)方案中的不同部分選擇不同的測(cè)試物料。例如，帶有結(jié)晶工序的無(wú)菌原料藥模擬，在早期步驟模擬階段可能需要液體物料，而結(jié)晶工序后的步驟需要粉末物料。 Inherent in the selection of a test material, and the decision to use a test material at all are considerations of potential adverse affects implicit in the use of a material. As a general rule, nothing should be introduced into the system, whether media or placebo, which may present a problem in subsequent processing. The material (if used) must be able to be easily removed from the equipment in order to prevent an increased potential for contamination of production materials that would later enter the system. 在選擇測(cè)試物料時(shí)的一個(gè)內(nèi)在問(wèn)題，決定究竟使用哪種測(cè)試物料，需要考慮物料使用時(shí)的潛在副作用。一般原則，不能在系統(tǒng)中引入任何物質(zhì)，不管是培養(yǎng)基或安慰劑，可能在隨后的加工中帶來(lái)問(wèn)題。 為防止增加隨后進(jìn)入系統(tǒng)的產(chǎn)品物料的潛在污染，使用的物料必須能從設(shè)備上容易移除。 See Appendix 1 for information on the selection, sterilization and use of test materials. 見(jiàn)附錄 1測(cè)試物料選擇、滅菌和使用的信息。 .

Process gases should be replaced with air to enhance microbial recovery. 工藝氣體由能促進(jìn)微生物回收率的空氣代替。 .

Simulation Without Material 無(wú)物料模擬 This is a simulation performed in the absence of materials. This approach has been used to evaluate operating procedures and personnel performing discrete aseptic manipulations, ., subdivision into final containers. The aseptic production processes are simulated using the procedures, personnel, equipment and ponents ordinarily utilized in the aseptic process. Immediately after pletion of the simulation, extensive microbial sampling of product contact surfaces and personnel is performed. Alternatively or in addition, a flush of the process train with a suitable medium can be employed. The surface sampling results are utilized to determine microb
