Paradigm Shift inside a gas chromatograph

Paradigm Flow Modulator and Shift Flow SplitterImprove GC peak capacity without sacrificing accuracy

Greatly expand chromatographic peak capacity across entire volatility ranges with the Paradigm Reverse Fill-Flush (RFF) Modulator. Reverse fill-flush modulators deliver comprehensive two-dimensional gas chromatography separation by filling a fixed volume sample loop with primary column effluent, before rapidly flushing the contents out of the sample loop and onto an orthogonal secondary stationary phase. Complete transfer of analytes between the respective stationary phases (comprehensive GCxGC) ensures excellent method repeatability and quantitation.

Features

  • Novel chromatography splitter featuring two channels of pressure assistance
  • Designed to work with the high flow rates needed for RFF modulation (approximately 20 mL/min)
  • Maintains constant split ratio between MS and FID throughout an entire run, even during oven temperature ramps

ChromaTOF Makes Modulation Simple

Paradigm does away with complicated offline flow calculators. The integrated ChromaTOF software features a simple user interface that automatically performs the necessary calculations for users. The resulting methods are guaranteed to feature complete analyte transfer, excellent peak shapes, and excellent chromatographic resolution.

A Shift Forward in Chromatographic Analyses

The Shift flow splitter is simple in design and appearance, but Shift’s novel splitting mechanism delivers long-sought functionality for complex sample characterization. Unlike traditional splitters, Shift maintains a constant split ratio between the MS and FID throughout the GC oven program. The result is unparalleled quantitative accuracy with minimal internal standardization required, greatly simplifying analyte and group-type quantitation for GC and GCxGC analyses.
