Modern systems consist of one or more computer-controlled metering pumps that can be programmed to vary the ratio of mobile phase components, as is required for gradient chromatography, or to mix isocratic mobile phases (i.e., mobile phases having a fixed ratio of solvents).

泵系统—HPLC 泵系统通过高压管路和设备将储液系统的流动相按设定的流量精确地输送通过柱子，最新的泵系统由一台或更多的计算机测量控制泵使得流动相组分能够按照程序变化改变比例，如有必要，可以进行梯度洗脱或混合均匀的流动相（i.e。，流动相可以是混合比例的溶液），然而，当操作压力达到或高于5000 psi，流速达到10ml/min的典型值时，预混合均匀的流动相各成分的比例就比泵控制的更精确。

Pumping Systems—HPLC pumping systems deliver metered amounts of mobile phase from the solvent reservoirs to the column through high-pressure tubing and fittings. Modern systems consist of one or more computer-controlled metering pumps that can be programmed to vary the ratio of mobile phase components, as is required for gradient chromatography, or to mix isocratic mobile phases (i.e., mobile phases having a fixed ratio of solvents). However, the proportion of ingredients in premixed isocratic mobile phases can be more accurately controlled than in those delivered by most pumping systems. Operating pressures up to 5000 psi or higher, with delivery rates up to about 10 mL per minute are typical.
