Clarity - Getting Started Connecting Autosamplers
45
time. The sampler is thus synchronized with the
GC by a signal wire (READY), alowing next
injection only after the GC gets to the READY
state. The Autosampler performs the injection
and starts the GC using another signal wire
(START). Any autosampler that is used in the
Clarity Active Sequence without
an AS Control
module must be synchronized by cable with the
Clarity station as well as with a chromatograph.
The IN
n
starting cable should be plugged into
the synchronization output (INJECTION) of an
autosampler or GC. The OUT
n
R cable should
be connected to the synchronization input
between GC and autosampler.
Note: Further information about Active Sequence is
available in chap. 4.3.2.2-3.of the Clarity User
Guide.
All commonly used autosamplers may be divided
in two groups:
• Autosamplers started by closing the contacts
on the input (
EADY
).
• Autosamplers started by opening the contacts
on the input (READY).
Variant A - started by closing the contacts
The first scheme displays the wiring of an
autosampler that is preparing to inject after
closing the contact on its input.
