反相是應(yīng)用zui廣的HPLC保留方式，但極性很大的化合物常常不能充分保留在低百分比有機(jī)相中，甚至不能保留在100%含水流動(dòng)相中。對(duì)于含有相同組分的樣品，正相洗脫順序與RPC中的洗脫順序正好相反。盡管正相LC在傳統(tǒng)上采用非極性有機(jī)流動(dòng)相和硅固定相，但如今，多數(shù)正相分離法均采用含水有機(jī)流動(dòng)相和極性較強(qiáng)的鍵合固定相。該HPLC方式目前普遍稱為HILIC，即親水作用色譜法。
如果采用強(qiáng)極性鍵合相（如TSKgel Amide-80），正相或親水作用色譜法可改善極性化合物的保留行為，其保留機(jī)理是使用乙腈與乙酸銨緩沖液的混合流動(dòng)相。與反相保留行為相反，在HILIC中，通過(guò)增加乙腈百分比可更長(zhǎng)時(shí)間地保留樣品中的極性成分。
