65 HPLC Glossary
High-pres-
sure side Devices and capillary which are under high
pressure in an HPLC system
HPLC High-pressure liquid chromatography (HPLC).
High-pressure liquid chromatography
Isocratic Mode of sample separation where the compo-
sition of a solvent remains constant
LAN Local area network (LAN). Network in which
HPLC devices and a computer are connected,
in order to control the devices.
LED Light-emitting diode
Low-pres-
sure side Devices and capillary which are under high
pressure in an HPLC system
LPG pump Pump configured to generate a gradient on the
low-pressure side. Only one pump unit is used
which contains small doses of the different sol-
vents. The solvents are mixed in small mixing
cycles by a valve block which is connected
upstream. The gradient is generated before the
pump.
Mixer Component for the homogeneous mixing of
solvents for the generation of a gradient
Mobile
Control Mobile application to control and program the
whole HPLC system via wireless LAN.
pH Measure for the acidic or alkaline character of
an aqueous solution.
Pressure
sensor Component for measuring the system pressure
Pump Device which conveys solvents in controlled
quantities into a system.
Quaternary
pump Pump configured to generate a gradient from
four solvents.
Solvent Flowing agent that transports the substances
to be separated or isolated through the column
(eluent, mobile phase)
Solvent
Selection
valve
Component of the pump that allows selecting
from two different solvents for every solvent
channel. With this mechanism the solvent can
be changed without having to manually
change the system.
Valve Device for varying the solvent flow.
