求一篇實驗注意事項的翻譯

翻譯下文: “這一過程需要注意以下事項: 1、第一次將支鏈淀粉-三(苯基氨基甲酸酯)的四氫呋喃溶液加入氨丙基硅膠中要呈稀粥狀,磁攪拌子剛好能夠自由轉動,一次加入過多會導致涂敷不均勻,待溶劑揮發(fā)磁攪拌子不能勻速攪拌后,再次加入支鏈淀粉-三(苯基氨基甲酸酯)的四氫呋喃溶液使氨基硅膠呈稀粥狀。這樣連續(xù)幾次,直到溶液加完。 2、溶液加完后,待溶劑揮發(fā)致使磁攪拌子不能攪拌時,用藥勺進行手工擠壓(動作要快,連續(xù)擠壓,否則結塊),直到溶劑完全揮發(fā)干,涂敷好的固定相呈原始硅膠的均勻細滑感,如果顆粒大小不一或有沙粒感要進行重新涂敷。 3、重新涂敷首先用異丙醇進行懸浮,將上浮的細小顆粒(合格)轉移至另一燒杯中,剩下的顆粒物進行適當?shù)募訜幔ú豢蛇^熱,保持攪拌),目的是揮發(fā)所含的異丙醇溶劑,待到溶劑沒有完全揮發(fā),還有一定的潮濕感,加入少量四氫呋喃,呈現(xiàn)粘稠狀便可,再進行人工擠壓,直到固定相顆粒都分散開。加入異丙醇重新懸浮,將合格品吸出,轉移合并到燒杯中。” 支鏈淀粉-三(苯基氨基甲酸酯) 直接用 ATPC表示 |

This process needs to note the following: 1, the first time amylopectin - (phenyl carbamate) THF solution was added to the aminopropyl silica gruel-like, magnetic stir just enough to free rotation, the first by adding too much can cause the coating uneven a magnetic stir bar to be solvent evaporation is not uniform mixing, again by adding a THF solution of branched-chain starch - (phenyl carbamate) was gruel-like amino silicone. This successive solution until end of the increase. 2. Solution and after until the solvent evaporation resulting magnetic stir bar can not be stirred, medication spoon hand-squeeze (action, continuous extrusion, or agglomeration), the stationary phase until the solvent completely evaporate dry coating good was uniform and smooth sense of the original silica gel, particle sizes or sand a sense to be re-coated. 3, re-coating First with isopropanol suspension, floating small particles (qualified) to be transferred to another beaker, and the remaining particulate matter to the appropriate heating (not overheating, keep stirring), the volatile contained isopropanol solvent until the solvent not completely volatile, there is still some moisture sense, adding a small amount of THF, showing thick can then manually squeeze, until the stationary phase particles dispersed. Isopropanol to re-suspension, qualified product suction, transfer the merged into the beaker. " Amylopectin - (phenyl carbamate) using ATPC 樓主你再看看,不行我在幫你修改. |
