PerkinElmer D-Swafer platform - N9306251

D-Swafer. PerkinElmer's Swafer™ platform is a micro-channel wafer technology, providing Clarus® 580 and 680 GC users with additional application flexibility, while delivering richer sample information, increased sensitivity, lower maintenance costs and increased sample throughput. 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. Heartcutting (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 backflushing - 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.
