Optimized Filtration of Ginger Formulation Pills Using Phenex PTFE Syringe Filters and Kinetex 2.6 μm Biphenyl LC Column

Filtration as sample preparation technique is useful to remove large particles before injection onto a column or it can be used to help filter samples before they undergo an additional sample preparation technique, such as supported liquid extraction (SLE) or solid phase extraction (SPE). This application displays the analysis of a ginger pill with and without proper filtration, as well as the subsequent carry over that results from an unfiltered sample.
