Hydropyrolysis (HyPy) Rig

HyPy

Background

Hydropyrolysis (HyPy) is a preparative method for samples that cannot be directly characterised by traditional techniques or where non-destructive recovery of the crucial portion of the sample is difficult. The fractions will then typically be analysed using techniques such as gas chromatography and mass spectroscopy.

How does Hydropyrolysis Rig work?

HyPy uses high pressure hydrogen and a specialist catalyst to recover the organic-derived portion – biomarkers – from highly contaminated or degraded samples. Biomarkers are “molecular fossils” that allow the origin of the sample to be determined.

The HyPy process achieves higher biomarker recovery than traditional solvent-based extraction methods.

HyPy removes functional groups from biomarker molecules while preserving the “carbon backbone” without structural or stereochemical alteration. Functional groups often interact with the stationary phase of a gas chromatography (GC) column and reduce chromatographic resolution.
