depends on the sample medium and the filter membrane's chemical compatibility. • For aqueous samples, hydrophilic-type membranes are preferred, such as cellulose acetate (CA) or polyethersulfone (PES). • For organic samples, especially with aggressive solvents, polypropylene (PP) or polytetrafluoroethylene (PTFE) filters should be used.
0.45-µm PTFE membrane before use. A 1 mL solution was pipetted into a 100-mL volumetric fl ask, followed by the addition of 2 mL of 1 % (V %) ammonia water. It was diluted to 100 mL with MeOH/H 2 O (10/90, V/V) and fi ltered through a 0.22-µm PTFE membrane before UHPLC analysis. Experimental Instruments This method was developed on an
