peer agreement (net): +2Elute a solid phase exchange resin column with aqueous acetonitrile solution Explanation: Elute a solid phase exchange resin column with 1.5 ml of aqueous acetonitrile solution containing 4.5 mg of potassium carbonate, ... -------------------------------------------------- Note added at 3 hrs (2009-02-16 06:11:41 GMT) -------------------------------------------------- solid-phase ion exchange resin column -------------------------------------------------- Note added at 4 hrs (2009-02-16 06:23:33 GMT) -------------------------------------------------- http://www.wipo.int/pctdb/en/wo.jsp?wo=2005044798 Abstract: ... A chromatographic column is loaded with a stationary phase, typically a silica particle having an organic ligand bound thereto. With a loading ratio of from about 50 to about 150 the impure preparation is acidified and passed through the column. ***The column is eluted with typically an aqueous solution of acetonitrile*** and the purified fentanyl is obtained in a specified cut. -------------------------------------------------- Note added at 4 hrs (2009-02-16 06:25:25 GMT) -------------------------------------------------- 淋洗液 = eluent -------------------------------------------------- Note added at 4 hrs (2009-02-16 07:06:55 GMT) -------------------------------------------------- Correction and clarification: Normally, “淋洗液” refers to an eluting solution, but in this sentence it refers to an eluted solution (洗出液). 淋洗剂 (洗脱剂) = eluting solution = eluent = eluant (e.g., the aqueous solution of acetonitrile in this case) 洗出液 = eluted solution = eluate = elutant (e.g., 含18F淋洗液 in this case) |
