TOSOH TSKgel Amide-80正相与亲水作用色谱柱
反相是应用zui广的HPLC保留方式，但极性很大的化合物常常不能充分保留在低百分比有机相中，甚至不能保留在100%含水流动相中。对于含有相同组分的样品，正相洗脱顺序与RPC中的洗脱顺序正好相反。尽管正相LC在传统上采用非极性有机流动相和硅固定相，但如今，多数正相分离法均采用含水有机流动相和极性较强的键合固定相。该HPLC方式目前普遍称为HILIC，即亲水作用色谱法。
如果采用强极性键合相（如TSKgel Amide-80），正相或亲水作用色谱法可改善极性化合物的保留行为，其保留机理是使用乙腈与乙酸铵缓冲液的混合流动相。与反相保留行为相反，在HILIC中，通过增加乙腈百分比可更长时间地保留样品中的极性成分。
