Petroleum-Petrochemical-Biofuel Markets Molecular Identification Separate and Identify complex organic mixtures in a single GC injection. Overcome Poor Peak Resolution Identify component classes in complex matrices even with incomplete chromatographic resolution. Functional Group Identification Compound classification based on common structural features, understand the entire molecular structure. Isomer Differentiation The IRD measures specific intra-molecular interactions ensuring distinctions between isomers. Isomers of equal molecular weight are more difficult to identify with mass spectrometry. Compliment GC Mass Spectrometry GC/MS – GC/IRD combination provides additional confirmation based on unique molecular properties. Library Searching  Formatted Vapor Phase Libraries for Qualitative analysis of unknown peaks. Who benefits from using the GC / IRD Molecular Detective^® • Petroleum Lab Managers • Contract Laboratories • Petrochemical Engineers • Biofuels Lab Managers.
