One On-Column Injector (OCI) is supplied as
standard equipment with the all 8610C and 310 GC mainframes. If
you require a second On-Column Injector, use this part
number. If you require a second injector OF ANY TYPE on your
GC, you must add an On-Column Injector first, and then upgrade
from there.
The OCI's low thermal mass and small size ensure that the syringe
needle deposits the liquid sample into the bore of the column
itself well inside the column oven, so that as the column
temperature increases, even high boiling point samples are
completely vaporized. This avoids boiling point discrimination or
other uncertainties, and the gradual volatilization of the sample
starting from a liquid droplet yields sharper peaks than flash
vaporization followed by recondensation.
The OCI is supplied with
carrier gas from the included Electronic Pressure Controller ( EPC ).
The carrier gas is filtered with a convenient internally mounted
molecular sieve filter which can be baked out by simply actuating a
switch on the GC's front panel.
INCLUDES: EPC circuitry,
1/8" injection port hardware, septum nut, capillary adapter,
digital pressure readout with 0.1psi resolution.
