How accurate is hplc
WebNote. A solute’s retention time in HPLC is determined by its interaction with the stationary phase and the mobile phase. There are a several different types of solute/stationary phase interactions, including liquid–solid adsorption, liquid–liquid partitioning, ion-exchange, and size-exclusion (see Figure 12.4).Section 12.5 deals exclusively with HPLC separations … WebHigh-performance liquid chromatography (HPLC) is a reliable and rapid method for identifying slow growing species of NTM.
