    • A system for and a method of providing an eluent composed of two different kinds of liquids being mixed at a set concentration and further a time varying concentration or mixing ratio, comprising (a) a step for transferring each of the two liquids by sucking under low-pulsation to on-off valves; (b) a step for periodically controlling the operation of the on-off valves; (c) a step for controlling the amount of each liquid supplied to the mixing region during each period of valve operation; (d) a step for substantially sucking the eluent formed by the above steps in the mixing region for discharging or supplying the same under the same low-pulsation, whereby a mixing of the two liquids under an atmospheric or a low constant pressure, can be effected and a supply of an eluent having a precisely controlled time varying concentration of each liquid can also be effected, and a system for providing such an eluent. Further a system for preparing such an eluent composed of more than two different kinds of liquids can be provided.
    • 一种提供由两种不同种类的液体组成的洗脱液的系统和方法,其以设定的浓度和更多的时间变化浓度或混合比混合,包括(a)通过在低温下吸吮两种液体的步骤 脉动到开关阀; (b)周期性地控制开关阀的操作的步骤; (c)在阀操作的每个时段期间控制供应到混合区域的每个液体的量的步骤; (d)用于在混合区域中基本上吸入由上述步骤形成的洗脱液的步骤,用于在相同的低脉动下排出或供应该洗脱液,从而可以在大气压或低压力下混合这两种液体 并且还可以实现每种液体具有精确控制的时间变化浓度的洗脱液的供应,以及用于提供这种洗脱液的系统。 此外,可以提供一种用于制备由两种以上不同种类的液体组成的洗脱液的系统。
