PREFACE
Thank you very much for purchasing Hitachi Model L-2100/2130
pump, which has been specifically designed for automatic
analysis in a liquid chromatograph system.
The Model L-2100/2130 pump is intended for use by persons
having a basic knowledge of chemical analysis.
Remember that improper use of analytical instruments,
chemicals or samples would result not only in wrong analytical
data but also in consequences adverse to safety.
Carefully read this instruction manual before attempting
operation. For proper use of the pump, please acquaint yourself
with it.
ABOUT THIS MANUAL
The operating procedures and maintenance/checkup instructions
for the L-2100/2130 pump are described in this manual.

IMPORTANT
Precautions on Electromagnetic Wave Interference
1. Possible Electromagnetic Wave Interference Caused by This Instrument
Where this instrument is used in a residential area or an
adjacent area thereto, it may cause interference to radio and
television reception.
To prevent this, use the specified system connection cables in
strict accordance with the instruction manual. The instrument is
designed to minimize possible electromagnetic wave
interference caused by it if the specified cables are connected
properly.
However, there is no guarantee that electromagnetic wave
interference will not be caused by the instrument.
If the instrument does cause interference to radio or television
reception, which can be determined by turning the instrument off
and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
•Reorient the antenna of the radio/television receiver.
•Increase separation between the instrument and the radio/TV
receiver.
•Connect the instrument to an outlet on a circuit different from
that to which the radio/TV receiver is connected.
2. Possible Electromagnetic Wave Interference Affecting This Instrument
Where this instrument is used near an intense electromagnetic
source, interference noise may be given to the instrument to
incur an adverse effect on its performance or functionality.
To present this, use the specified system connection cables in
strict accordance with the instruction manual. The instrument is
designed to minimize possible electromagnetic wave
interference affecting it if the specified cables are connected
properly.
However, there is no guarantee that electromagnetic wave
interference will not occur in the instrument. If the instrument
does incur electromagnetic wave interference, which can be
determined by turning on and off possible sources of
electromagnetic interference nearby, the user is encouraged to
try to correct the interference by one or more of the following
measures:
-4-
•Reorient the instrument.
•Increase separation between the instrument and possible
sources of electromagnetic interference.
•Connect the instrument to an outlet on a circuit different from
that to which possible sources of electromagnetic interference
are connected.
•Check that any other device connected with the instrument is
not affected by electromagnetic interference.

1. OUTLINE
The liquid chromatograph system consists of a pump for feeding
an eluent, 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 degasser 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.
1.1 Isocratic System
The isocratic system has a simple configuration in which single-
solvent analysis is performed.

(1) An eluent is fed by the pump through the degasser.
(2) Asample is injected from the autosampler.
(3) The injected sample is separated through the column which
is maintained at a constant temperature by the column
oven.
(4) Each component separated from the sample is then
detected as a signal by the detector.
