Introduction to the Thermostatted
Autosampler
The Agilent 1100 Series thermostatted autosampler is designed for use with
other modules of the Agilent 1100 Series LC system, with the HP 1050 Series,
or with other LC systems if adequate remote control inputs and outputs are
available. The thermostatted autosampler is controlled from the Agilent 1100
Series control module or from the Agilent ChemStation for LC systems.
The specially-designed thermostattable sample trays holds either
100 × 1.8 ml vials or two wellplates and 10 × 1.8 ml vials.
The ALS thermostat contains Peltier-controlled heat exchangers. A fan draws
air from the area above the sample vial tray of the autosampler and is then
blown through the fins of the cooling/heating module. There it is cooled or
heated according to the temperature setting. The thermostatted air enters the
autosampler through a recess underneath the specially-designed sample tray.
The air is then distributed evenly through the sample tray ensuring effective
temperature control, regardless of how many vials are in the tray.
In cooling mode condensation is generated on the cooled side of the Peltier
elements. This condensed water is safely guided into the leak system.
