Ibhodlela lokuhlunga lihlanganisa isirinji, isihlungi sesirinji nezitsha zesampula zibe umkhiqizo owodwa. Isho isikhathi esiningi futhi igwema ukungcola. Sinolwelwesi oluhlukahlukene olunikeza izixazululo zokuhlukanisa nokuhlanzwa zeningi lezidingo zakho ezifana nokukhipha izinhlayiya kumasampula alungiselelwa i-HPLC kanye nokuhlaziywa kwe-UHPLC.
