Figure 19 Quick change valve in TCC
Up to three TCC can be “clustered” to allow advanced applications such as
switching between eight columns for automated method development or to
make additional columns available for different applications. Thus, the column
to be used becomes a simple method parameter. This requires two 8 position/9
port valve heads, one each in two of the TCCs. Clustered TCC are represented
by the software as one unit with one interface for ease of operation.
Further improvements compared to earlier designs include better thermal
insulation, better capillary guides and a “door open” sensor so that methods
can define that the door must be closed – especially useful for low or
high-temperature methods.
