Sample Text 用十八烷基硅烷鍵合硅膠做為填充劑(4.6mm*250mm,5μm);以0.2mol/L硫酸鹽緩沖液(取無(wú)水硫酸鈉28.4g,加水溶解后,加磷酸2.7ml,乙醇胺調(diào)節(jié)pH值至2.3,加水至1000ml)-乙腈(74:26)為流動(dòng)相;柱溫為40℃;檢測(cè)波長(zhǎng)為214nm;流速1mL/min。實(shí)驗(yàn)樣品用0.01mol/L鹽酸溶液制成40u/mL的溶液,注入液相色譜儀20μL,記錄色譜圖;另取胰島素對(duì)照品適量,同法測(cè)定。按外標(biāo)法以峰面積計(jì)算效價(jià)。 灰常感謝。 |

| Use a column packed with octadecylsilane chemically bonded silica(4.6mm * 250mm,5μm),0.2mol/L sulfate buffer(prepared by dissolving 28.4g of anhydrous sodium sulfate in water and adding 2.7ml of phosphoric acid, adjusting the solution with ethanolamine to pH 2.3, diluting with water to 1000ml)and acetonitrile(74:26)as mobile phase with a flowrate 1ml /min, maintain the column temperature at 40℃,the detection wavelength is 214nm.Dilute a quantity of sample with 0.01mol/L HCl solution to produce a 40u/mL solution, inject 20μL into the column, record the chromatograms. Repeat the operation, using a quantity of insulin CRS.Calculate the units with respect to the peak area obtained in the chromatogram by the external standard method. |
