A new method was described for simultaneous determination of Z.mobilis metabolites by reversed phase-high performance liquid chromatography(RP-HPLC).The samples were analyzed on a C18 column(Waters SunFireTM C18,Φ 416 mm×150 mm,5 μm),and the mobile phase was 10 mmol/L pH2.5 KH2PO4 solution with a flow rate of 0.8 mL/min.Under this optimized condition gluconate,pyruvate,lactic acid and acetic acid were completely separated and determined with a photodiode array detector(PAD).The IC-PakTM on-Exclusion column(...
