Molecular Identification for Gas Chromatography Benefits of the Molecular Detective^® Unique Design The Molecular Detective^® is the only Analytical Infrared Instrument designed from the chromatographer’s point-of-view. The result is an instrument that requires a minimum of bench space with optimized, dedicated optics for highest sensitivity. The IRD software has been designed to interface with GC Software and provide instrument control, data acquisition and analysis in real time. Performance Benefits • Molecular Identification – Separate and Identify complex organic mixtures in a single GC injection. • Increased Productivity – GC/IRD combines the separation power of the GC with the molecular identification of the IR. • 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 distinction between isomers.  Isomers of equal molecular weight are more difficult to identify with mass spectrometry. • Compliment GC/MS – The GC/IRD combination provides additional confirmation data based on unique molecular properties. • Increased Peak Resolution – Identify component classes in complex matrices even with incomplete chromatographic resolution. • Essential FTIR Data Analysis - Software simplifies the process of collecting, analyzing and reporting IRD data. • Library Searching – Formatted Vapor Phase Libraries for Qualitative analysis of unknown peaks. Uprecedented Sensitivity  The IRD detects 100 picograms of isobutyl methacrylate or dodecane at a signal-to-noise ratio of 3:1 – several times more sensitive than any other Vapor-phase flow cell FTIR now available. The IRD has the sensitivity and stability required to make capillary GC/FTIR practical in the analytical laboratory. MSD Interface Separately, GC/IR and GC/MS are both very powerful analytical tools. GC/IR can provide molecular level analysis of unknowns without destroying the compound. GC/MS can provide mass fragmentation data and molecular weight but not geometric model information. With the addition of the ASAP Analytical transfer line, the IRD can be coupled to the MS and provide this molecule geometry from a single injection.
