normal phase liquid chromatography 예문

• Use of materials such as silica gel as stationary phase with neat or mixed organic mixtures are used in techniques termed normal phase liquid chromatography ( NP-LC ).
• Methods in which the stationary phase is more polar than the mobile phase ( e . g ., toluene as the mobile phase, silica as the stationary phase ) are termed normal phase liquid chromatography ( NPLC ) and the opposite ( e . g ., water-methanol mixture as the mobile phase and C18 = octadecylsilyl as the stationary phase ) is termed reversed phase liquid chromatography ( RPLC ).
