3: MPS-TEX
MPS-TEX offers the possibility for liquid injection in the TDU unit operating in cold mode.
Inside an empty TD tube, a micro vial is placed, and the after injection a programmed warm up of the TDU unit is performed.
The solvent and other volatile analytes will evaporate and get focused on the CIS which is operated in cold mode.
Non volatile matters will stay in the microvial protecting the inlet and the GC column.
