堿性去活硅膠,更好的重現(xiàn)性和色譜峰對(duì)稱性
使用早期硅膠填料時(shí),若要得到較好的色譜峰,通常需要在流動(dòng)相中添加酸(醋酸)或堿(三乙胺),使其與硅醇基產(chǎn)生競(jìng)爭(zhēng)性結(jié)合,從而改善色譜峰形。當(dāng)使用了合適的流動(dòng)相添加劑時(shí),色譜峰形會(huì)得到明顯改善。通常需要很高的添加劑濃度——多數(shù)情況下達(dá)到 1% (體積比)或更高,這樣才能使所有殘留硅醇基都與添加劑結(jié)合,而不影響分析物的色譜峰形。但是高濃度添加劑常常嚴(yán)重降低色譜柱壽命和方法重現(xiàn)性。
