Agilent 7890 GC with 5977 MSD, 7697 Headspace Sampler & 7693 AS

What you are buying

Environmental, forensic, and food-safety methods that identify and confirm compounds by mass run on the GC-MS the Agilent 5977A MSD delivers. This system pairs the 7890 GC and 5977A MSD with both a 7697 headspace sampler and a 7693 liquid autosampler, sharing one GC inlet through a transfer line interface accessory. The headspace sampler pulls vapor from sealed vials for volatile analysis; the liquid autosampler injects directly for routine compounds. GenTech rebuilds and tests the GC, the samplers, the source, and the analyzer, then verifies the system end to end.

Every unit moves through the GenTech Certified process. Solution Scientists disassemble and inspect each module, replace all consumables and degraded wear components, then tune and calibrate the instrument and verify performance against OEM and published benchmarks using known reference chemicals. The instrument ships with its verification report. A certified-refurbished system gives you that performance without the capital cost or the lead time of a new purchase.

What Agilent says about this platform

The 7697A Headspace Sampler builds on the 7890 GC and 7693A automatic liquid sampler platform, available in a 12-vial configuration for lighter sample loads or a 111-vial configuration with three priority positions for late-arriving samples. A transfer line interface accessory lets the headspace sampler and the ALS share the same GC inlet. An automatic vial leak test checks each vial during pressurization without a separate manual calibration step. Independent control of vial pressurization and column head pressure keeps back pressure from affecting sample transfer. Multiple headspace concentration mode runs up to 100 extractions per GC start; multiple headspace extraction mode runs up to 100 extractions per vial. Temperature zones for the oven, the valve and loop, and the transfer line each set in 1-degree increments with 0.1-degree resolution. The sampler supports 10, 20, or 22-milliliter vials without an adapter and runs under OpenLab CDS, MassHunter, or Waters Empower software.

What each component does

Gas chromatograph

Separates the mixture on a capillary column under programmed temperature and electronic pneumatic control. The 7890 front end runs the same inlets, detectors, and Capillary Flow Technology as a standalone GC.

Headspace sampler

The 7697 pulls vapor from a sealed vial for volatile analysis, sharing the GC inlet with the liquid autosampler through a transfer line interface accessory.

Liquid autosampler

The 7693 draws a precise volume from a vial and injects it directly onto the column for routine, non-volatile compounds.

Transfer line and ion source

Carries the separated compounds into the 5977A MSD at controlled temperature. Electron ionization produces reproducible, library-searchable spectra; chemical ionization preserves the molecular ion for confirmation.

Mass analyzer

The quadrupole filters ions by mass. It scans a full spectrum for identification or holds on selected ions for the lowest detection limits in quantitation.
