System Components
A totally new optional add-on module, the Flexible Cube, works seamlessly
with the autosampler to provide additional capabilities. With the addition of
the new Flexible Cube module, which comprises a 500 µl syringe pump, one
low pressure valve and two high pressure switching valves further options
become possible. For instance, the flow-through injection system can be
replaced by a fixed injection loop using the syringe pump and valving of the
Flexible Cube to fill the sample loop. The advantage of this configuration is
that it eliminates the delay volume from the autosampler and so may be
preferred in some fast-gradient high-throughput situations. The trade-off is
that the flexibility of variable volume injection is turned off and some sample
is wasted in flushing the loop. Other tasks such as automatically back-flushing
the injection needle seat after injection are possible with the Flexible Cube
giving further confidence that carryover of difficult compounds or blockages
caused by dirty samples can be routinely avoided.
The autosampler sample rack has 10 fixed positions for 2 ml vials and two
removable trays, which may or may not be identical, selected from:
• Tray for 2 ml vials with 54 positions
• Microtitre plate with 96 well positions (various heights configurable)
• Microtitre plate with 384 well positions (various heights configurable)
If required the autosampler can be thermostatted from 4 °C to 40 °C by the
addition of the autosampler temperature control module.
