Autosampler and Autoinjector Setup
When you hook up an autoinjector or autosampler to the HTEC-500, do not remove the manual injector
from the system. If you ever have problems with the HTEC-500+Autosampler/Autoinjector, the manual
injector will be needed to diagnose which part is the problem.
It is recommended that the manual injector is to be located upstream of the autosampler/autoinjector.
Leave the manual injector at the inject position while you are using the other injectors so that the
sample loop on the manual injector can be kept clean by the mobile phase.
If the sample needs to be injected from the manual injector located upstream of the external injectors
(autoinjector or autosampler), please keep these external injectors at the load position. Then the
injected sample will not go through the sample loops on the external injectors. The obtained peaks will
have a good shape. Otherwise, the peak will be broad and the retention times will become longer.
