homing: the process of the turret, syringe carriage, syringe plunger, vial
gripper, and tray arm moving to their home positions.
INET: an acronym which stands for instrument network.
injection: the injector motion that delivers the sample to the inlet or column
of the gas chromatograph.
injection port: see inlet.
inlet: the terms inlet and injection port are used interchangeably in this
manual.
interaction: the attraction or repulsion between two chemical species in a
specific chemical environment. For example, some sample components
interact with a glass inlet liner unless the liner is deactivated.
LED: an acronym which stands for light-emitting diode.
list: to present the contents of a program or file in readable form, often a
printed copy or displayed on an integrator chart or computer screen.
nanoliter injection: an adapter to the injector that enables injection volumes
from 0.1 µl to 4.0 µl.
needle fractionation: the boiling off of sample in the syringe needle during
injection. Not only does residual sample in the needle enter the inlet, but the
low boiling components boil off first. See fast injection.
parameter: an element, sometimes optional, that provides additional
information to a command.
peak area discrimination: used to describe a chromatogram with peak areas
that are not reproducible.
prompt: a message or symbol requesting you to enter information. For
example, the run parameter prompts of the 3396A Integrator when you are
editing a sequence.
