SUPERSIPPER
The SuperSipper is an optional accessory that enables samples to be drawn into
a flowcell of the user's choice for automatic measurement. After the
measurement is complete the sample may be sent to waste or returned to its
original vessel. A continuous pumping mode allows the system to be washed
through when required, e.g. between applications.
This section describes the operation of the SuperSipper with the Local Control
software. Full details of the installation and operation of the accessory are
described in the SuperSipper Installation and Maintenance Manual (9499 230
29611) supplied with the SuperSipper.
To operate the SuperSipper, install as described in the above manual. Present
the sample to the SuperSipper and press the switch. The required sample
volume will be drawn into the tubing. When the system beeps remove the
sample and the required air gap will be drawn in. Once the measurement has
taken place press the switch again. The sample will be pumped out of the
flowcell either to waste or returned to the sample vessel.
When the sipper is connected a status box is displayed on the right hand side of all
the method screens that indicates the presence of the SuperSipper and its status.

In STANDBY mode, the sipper pumps a small volume approximately every 30
minutes. This is to change the point at which pressure is applied to the Sipper
tubing, thus preventing the formation of a permanent kink. The first 6 movements
are in the Return direction, and the next 6 are in the Waste direction. The total
volume pumped is sufficiently small as to ensure that any sample present remains
in the tubing. When the sipper is operated normally, its clock is reset and the
Standby process re-starts.
