General Features

The following features make the DSC Autosam-

pler CE a unique and flexible tool:

The Autosampler CE makes decisions on

the basis of current system status, operator-

directed parameters, and computer-directed

instructions.

The mechanical fingers that grip the sample

pans and cell lids enable the Autosampler

CE to handle objects weighing from

milligrams to tens of grams with more

reliability than vacuum-grip systems. Open

pans can be handled as safely as closed

pans with the Autosampler CEs tactile-

feedback gripper fingers. The tactile-

feedback programming also detects

improperly gripped or dropped objects and

prevents the grippers from puncturing the

floor of the DSC cell furnace.

The Autosampler CE can be operated

automatically through the TA controller or

manually through its own keypad. Under

manual operation, you can directly control

turret movement to calibrate and test the

Autosampler CE, whereas automatic

operation (using

Thermal Solutions/

Advantage

) offers the benefits of

preprogrammed runs that can be left to be

executed overnight.

If the multi-instrument option is installed on

your controller, you are free to run other

instruments (

e.g

., TGA, DMA, TMA) while

the Autosampler CE takes care of DSC
