為什么使用HILIC?

盡管反相液相色譜(RPLC)是至今應(yīng)用zui廣的色譜分離技術(shù),它能與各種常規(guī)的檢測(cè)方法結(jié)合,解決多種分析應(yīng)用問(wèn)題,但對(duì)某些分析物,特別是極性和親水性化合物卻無(wú)法或很少保留。長(zhǎng)期以來(lái),人們采用正相液相色譜(NPLC),并使用不利環(huán)保的非水溶性流動(dòng)相如己脘或環(huán)己脘來(lái)分析這些物質(zhì)。

但是在這種實(shí)驗(yàn)條件下,很多極性和親水化合物往往很難溶解,從而限制了NPLC的應(yīng)用范圍。從現(xiàn)在起有了另一種新的解決辦法,即選用親水作用液相色譜-HILIC。

什么是親水作用色譜(HILIC)

親水作用液色譜(Hydrophilic Interaction LiquidChromatographyHILIC) 是一種直接分離極性和親水性化合物的色譜技術(shù),為了便于理解,我們可以把它看作為是一種反相色譜溶劑做為流動(dòng)相的正相色譜。

因此HILIC是:

親水性的固定相

以水、有機(jī)溶劑和緩沖液作為流動(dòng)相洗脫劑


常見(jiàn)的HILIC方法采用50-90%有機(jī)溶劑和一定比例的水,并且含有低濃度的緩沖鹽。如乙腈//醋酸銨體系

HILIC方法中,洗脫順序和反相色譜正好相反,即極性越大,保留時(shí)間越長(zhǎng)。
