3.4 Fraction Collector Compartment
The fraction collector compartment of the device accommodates a
carousel with four color-coded segments and a needle drive to move
needle unit in Y and Z directions.
The device supports the same sample racks and well plates with a
footprint as specified by the Society for Biomolecular Screening (SBS
footprint) like the Vanquish Split Samplers.
Besides, the Fraction collector compartment provides the following
features:
•
Thermostatting. See Thermostatting (

page 43) .
•
Rack type identification and verification, empty segment detection
and inventory management. See
Carousel (

•
Compartment light.
3.4.1 Thermostatting
Temperature control is available for the fraction collector compartment.
Circulating air is used to cool or heat the fraction collector compartment
to the set temperature, thus allowing precise equalization of the sample
temperature.
To achieve an optimum thermostatting performance, keep the front
doors of the device closed during fraction collection. Open the front
doors only if required, for example to load the device with sample
containers.
The device allows thermostatting in the range of +4 °C and +40 °C.
Cooling of the collected fractions is possible to max. 23 K below ambient
temperature.
Depending on the ambient humidity, condensation liquid may occur
during cooling. A condensation drain system in the device actively
removes any occurring condensation liquid from the fraction collector
compartment.
The drain system includes a drain pump and one inlet tubing going to
the rear side of the device to drain out condensation water accumulated
inside the fraction collector compartment at fixed interval.
