610 Checkout Chromatograms
This section contains typical examples of test sample chromatograms. They
may be used as a general guide to instrument performance.
Injection volumes listed with operating conditions in the following
chromatograms do not necessarily indicate total absolute volume injected.
Volume given is simply the graduation (plunger position) read from a standard
10 mL syringe. For a heated inlet, actual sample volume injected will also
include an additional 0.4 to 0.7 mL, the volume of sample volatilized from
inside the syringe needle. For the dedicated, on-column inlet (unheated), the
syringe plunger position more accurately reflects the true injected volume.
Also note that the following procedures and results are intended only to
provide evidence of a properly functioning inlet and/or detector system; they
are not necessarily suitable to test a given system against its specification
limits.
For more detailed information about instrument specifications, see the
Standard Operating Procedures Kit, Part No. G1530-61210.
Note: 30 m × 0.32 × 0.25 µm columns may be substituted. Slight elution time
differences can be expected but the order of elution will remain the same.
