A Comparative Study on Peaking of Gentamicin Sulfate 1. Experimental method Cometro high performance liquid chromatography system; Chromatography column: Inertex C18 150 * 4.6mm, 5μm; Evaporative light scattering detector (SOFTA M300S): SC 30 ℃ DT 70 ℃ CL 20 ℃; Gain: Normal; Flow rate: 1.0ml / min, 0.8ml / min, 0.6ml / min; Sample: Gentamicin sulfate sample 2.5mg / ml; 2. Experimental results 1. Flow rate 1.0ml / min 2. Flow rate 0.8ml / min 3. Flow rate 0.6ml / min 3. Conclusion It can be seen from the comparison of different flow rates that the best effect is achieved when the flow rate is 1 ml / min when all samples can be completely separated.
