Abstract:
Flow modulated comprehensive two-dimensional gas chromatography is a rugged and low cost alternative to cryogen-based thermal modulators. Construction of a diffusion bonded single-plate device can further enhance simplicity and robustness by incorporating an internal collection channel, projection welded gas connections, and leak-free metal ferrule column connections. The device is well suited for the analysis of permanent gases and light hydrocarbons which are too volatile to be trapped efficiently using thermal modulation. In this paper, the separation of light hydrocarbons is demonstrated using a single-plate reverse fill/flush differential flow modulator with PLOT columns.
