D-Swafer

Perkin Elmer D-Swafer; The D-Swafer is based on the classical Deans' Switch principle, but may be configured in multiple ways to provide a variety of features: Inlet, column, and detector switching and isolation - provide maximum application flexibility Heart cutting (Deans Switch) - allows separation of selected peaks within a complex sample matrix Solvent venting/column-bleed venting - removes undesirable materials from the GC system Sample back flushing - for removing heavy sample residue or carrier gas swapping Polarity tuning - allows tweaking of column selectivity during chromatography to optimize difficult separations Selective peak attenuation - enables specific peaks to be attenuated to monitor a larger dynamic range - PE
