Top: experimental calibration curve of the gear wheel pump for isopropanol and water, obtained under identical experimental conditions as for the kinetic studies. Bottom: characteristic function of the capacity of the syringe pump. Open triangles: 20 ml syringe; open circles: 10 ml syringe; filled circles: 5 ml syringe; filled triangles: 2 ml syringe. The inset shows an enlargement of the most commonly used driving speed range. |
