Description
Type: GCIR Interface for Nicolet FTIR
Unit Size: Each
The GC-IR Interface is optimized for analyzing small elution volumes found in high-resolution capillary columns. The system achieves excellent sensitivity, typically in the low nanogram range for volatile species. The combination of the GC-IR Interface with Thermo Scientific Nicolet FT-IR spectrometers provide an effective tool for analyzing multi-component organic samples, including solvents, reactants, pharmaceuticals, petrochemicals, and environmental samples. Advanced FeaturesCapillary column can be inserted directly into the lightpipe, eliminating component degradation and peak broadening in the transfer lineGold-coated lightpipe with long pathlength and small inside diameter maximizes the infrared response for low nanogram sensitivityPatented MCT-A detector contributes to the system's unmatched sensitivity and dependabilityPinned-inplace Smart detectors can be interchanged with the bench detector without alignmentSmart detectors, with a plug-and-play feature, provide instant recognition of the detector and its locationSmart detectors feature a patented mechanism to prevent the formation of ice on the detector element and provide an 18-hour liquid hold-timeOmnic Series SoftwareThe GC-IR Interface uses Windows™-based OMNIC Series software for data collection and manipulation, incorporating the power and control needed to perform advanced GC functions with the simplicity of the OMNIC software interface.Graphical user interface with point-and click operations makes the software extremely intuitiveProvides a real-time display of the Gram-Schmidt reconstruct, (IR Chromatogram) Chemigrams, and infrared spectra while data are being collectedData are stored as multi-files, allowing all data in the set to be processed using a single software commandSingle spectra or coadded regions can be extracted for compound identification by using our wide range of available vapor phase spectral libraries.2-D contour and 3-D waterfall display of GC data provides enhanced processing capabilities for complex sample mixtures SpecificationsOptics and HardwareBaseplate: Precision-cast baseplate with Lock-in-Line connection to the right or left side of Nicolet FT-IR spectrometers, providing precise optical alignment of the GC-IR InterfaceOptics: Efficient optical design using three mirrors to direct the collimated beam from the spectrometer, through the gold-coated lightpipe and onto the MCT-A detector located in the GC-IR InterfaceLightpipe: Gold-coated glass flow cell with gold-coated alloy end caps; lightpipe seals made of a high-temperature polymer capable of operating continuously at 325°C; low dead volume design (15cm length, 1.0mm ID) that produces the highest absorbance with minimal peak broadeningTransfer Lines: Stainless steel, glass-lined and thermally insulated; direct insertion of the GC column, which provides a totally inert passage of chromatographic components into the gold-coated lightpipeMake-up Gas: The addition of an adjustable make-up gas controller to the GC oven to maintain linear velocity and chromatographic peak integrity within the lightpipe; make-up gas flow around the outside of the column, directing the column effluent throughout the lightpipe; typical flow: 0.20mL/min.Temperature Control: Digital, solid-state temperature controllers for individual control of lightpipe and transfer line temperature; software selectable from ambient to 325°C°Detector: Stainless steel; recommended: high-sensitivity MCT-A (range 11,700 to 600cm^-^1); optional: MCT-B (range 11,700 to 400cm^-^1); smart design with plug-and-play interchangeability with the detector position on the spectrometer with no alignment required; a proprietary mechanism feature to prevent the formation of ice on the detector element and provide an 18-hour liquid nitrogen hold-timePerformance CharacteristicsScan Speed: Able to collect, co-add up to 7 scans at 8cm^-^1 spectral resolution, process, display, and store to hard disk IR spectra and IR chromatograms in real-time in less than 1 second (with a minimum of a 400 MHz Pentium™ PC); production of spectra from double-sided interferograms for the highest signal-to-noise ratioPeak–to–Peak Noise: Less than 1.0 × 10^-^4 Abs. peak-to-peak noise measured at 8cm^-^1 resolution with a 4-second collection time using the KBr beamsplitter, MCT-A detector, and lightpipe at 200°C Compatible with:GC Oven Compatibility: Interfaces to TRACE GC Ultra ovens; for compatibility with other GC ovens—please inquire
