Gas Chromatograph Mass Spectrometer (GC-MS)
Agilent 7890A Gas Chromatograph and Agilent 7820 Gas Chromatograph
Model: Agilent 7890A Gas Chromatograph and Agilent 7820 Gas Chromatograph
Location: 014 Brauer Hall
Description: GC-MS combines two powerful techniques to provide the identification of compounds with low detection limits and the potential for quantitative analysis. Liquid, gaseous and solid samples work well with GC-MS analysis. However, analyzed compounds are typically volatile and semi-volatile.
Agilent 7890A Capabilities:
- Equipped with two detectors: a Flame Ionization Detectors (FID) and an Electron Impact Ionization Mode Mass Spectrometer (MS) or 5975C Inert XL MSD with triple axis detector. The combination of the GC with each of these detectors provides a unique capability, from identifying trace compounds (MS) to accurately quantifying hydrocarbon species (FID).
- The FID has been coupled with a Polyarc system. The Polyarc system has a catalytic micro reactor that converting all organic compounds to methane molecules prior to their detection by the FID. In doing so, the Polyarc system reduces the need to perform time-consuming calibrations by creating a uniform detector response for truly universal carbon detection.
Agilent 7820A Capabilities:
- Retention Time Locking (RTL) provides improved data consistency by maintaining exact retention times from injection to injection, column to column, instrument to instrument, and lab-to-lab.
- Electronic Pneumatics Regulation (EPR) provides the simplicity of manual operation with high-precision digital display of pressure/flow and superior ease-of-use, compared to traditional manual pneumatics systems.
- Great fit for routine applications using a single quadrupole mass spectrometer
- Auto-ranging FID provides the ability to detect and quantitate from parts per billion (ppb) to parts per thousand in a single injection.
- Inlets options include split/split less, packed, purge packed, and on-column inlets
- Complex mixtures of chemicals are separated, identified and quantified.
- Measure the 13C mass distribution in amino acids for metabolic flux analysis.
- Quantitative measurement of lipids and organic acids.
- Identify and quantify lipids accumulated in bioprocessing.
- Detection of dibenzofurans, dioxins, herbicides, sulfur, pesticides, phenols and chlorophenols in air, soil and water
