Test Sample Chromatograms

This chapter contains typical examples of test sample chromatograms. They may be used as a general guide to instrument performance.

It is assumed that both the instrument and proper test column are installed, that general keyboard control is understood (temperature control, defining signal output, etc.), and that specific operating information for the given inlet and detector is also understood. If not, consult the HP 5890 SERIES II Operating Manual as necessary before proceeding with test chromatogram procedures.

Note that 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 ¿l syringe. For a heated inlet, actual sample volume injected will also include an additional 0.4-0.7 ¿l, the volume of sample volatilized from inside the syringe needle. For the dedicated on•columninlet (unheated), the syringe plunger position more accurately represents 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.
