Introduction
A number of different sample application techniques are available. The sample can be
applied either directly onto the column using the Sample pump, or via a loop. A loop can
be filled either manually or by use of the Sample pump. This section describes sample
application using a syringe to manually fill a capillary loop. The two stages of the sample
application are described in the table below. For detailed instructions and information
regarding the different sample applications techniques, see User Manual.
