event is the operation of a device external to the data system but integral to the analytical run. A
hardware event can be a valve rotation, opening or closing a split vent, activation of an autosampler
sequence, or operation of an electrical switch at a precisemoment during the run. PeakSimple also
gives you control over a comprehensive list of non-hardware events, such as integration events, data
system signal control events (zero, reverse), and DOS command events. Events are controlled
automaticallywith
Event tables
that use the system clock, which starts at 0:00with each run. Using
PeakSimple
Event tables
enhances the reproducibility of the resulting chromatograms by ensuring
repeatable actuation of devices from run to run.
Theeight timedevent output signals arecalled
relays, andarenamedA-H. Forexample,when
an SRI GC is equipped with a 10-port gas
sampling valve, its rotation/actuation is
controlledby a relay: relayOFF=valve in the
LOAD position; relay ON = valve in the
INJECT position. The relay assignments for
any given instrument are printed on the side
panel (right hand side for GCs, left-hand side
forHPLCs).
Usersmaymanuallycontrol any relayevent, either during the runorwhile in
stand-bymode,byusing the
Relays/pump
window. ClickonViewandchoose

with theappropriate letter. Activatea relaybyclickingon its letter; itbecomes
highlighted to show its ON status. You can also toggle the relays from the
keyboard by holding the control key (Ctrl) while pressing the letter of the
relay: Ctrl+C, Ctrl+H, etc.
This list of assigned relay functions is printed on the side
