The LCTech sensor allows reliable evaporation nearly to dryness or as usually to a final volume of 30 to 100 µL for the PCDD/F-Fraction (F2) or a final volume of 300 to 500 µL for the PCB-Fraction (F1). Even with rinsing, the subsequent transfer into the insert of a GC-vial is possible. Due to design and the special technology, memory effect that would lead to unwanted further evaporation after the system has been switched off, is reliable excluded.
