1.2 Configuration of Liquid Chromatograph System
1.2.1 Isocratic System
The liquid chromatograph system consists of a pump for feeding
a mobile phase, a sample introducing section (autosampler,
manual injector) for injecting a sample, a column for
chromatographic separation of the injected sample, a column
oven for maintaining the column at a constant temperature, and
a detector section for detecting a signal of a separated
component of the sample.
In addition, a degassing unit for deaerating an eluent, a gradient
device for varying a mixing ratio of eluents with time, and other
optional devices are incorporated in the system.
The isocratic system has a simple configuration in which single-
solvent analysis is performed.
