2.2 Application
The autosampler is combined with a liquid chromatograph and
used for injecting a sample.
2.3 Operating Principle and Functional Description
2.3.1 Configuration of Flow Path
The configuration and the flow path of the Chromaster 5210
autosamplers are shown in Fig. 2-5 and 2-6. Sample vials are
placed in the form of a rack. The sample rack moves along the
transverse axis (X), and the arm moves along the longitudinal axis
(Y) and the vertical axis (Z), whereby the needle can move freely
among the sample vials, wash port and injection port. To the
needle, a valve and a syringe are connected, so a sample can be
aspirated and dispensed.
After a sample is aspirated through the needle tip, the needle is
washed in the wash port and the sample is led into the flow path
with the injection valve set on the injection side.
When the UI pad (option) is mounted, all operations can be carried
out by the keys on the operation pad while checking display on the
screen.
