Agilent 6890N GC with 5973N MSD

What you are buying

Environmental, forensic, and food-safety methods that identify and confirm compounds by mass run on the GC-MS the Agilent 6890N and 5973N deliver together. The 6890N separates the mixture on a capillary column; the sample crosses a heated transfer line into the 5973N; the source ionizes each compound; the quadrupole scans the mass range or watches selected ions for trace quantitation. GenTech rebuilds, plumbs, and tests the GC’s inlets, detectors, and flow path, then cleans and calibrates the MSD, and verifies the complete 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

Electronic pneumatic control on the 6890N meters carrier and detector gases to 0.001 psi and 0.05 mL/min, compensating for changes in ambient pressure and temperature. The oven programs from 4 to 450 degrees Celsius across 20 ramps and 21 plateaus. The 5973N MSD attached to it runs on either a 90-liter-per-second vapor-diffusion pump or a 250-liter-per-second turbomolecular pump, with chemical ionization available only on the turbo-pump configuration. An independently heated electron-ionization source and an independently heated hyperbolic quadrupole mass filter let the source and analyzer run at separate temperatures. A triode ionization gauge tube monitors vacuum pressure. Chemical ionization hardware, where fitted, produces classical CI spectra that include molecular adduct ions, using a methane or isobutane reagent gas through a dedicated gas purifier. The detector draws up to 900 watts and weighs 194 pounds.

What each component does

Inlet

Vaporizes the sample and delivers it to the head of the column. Split/splitless handles routine concentrations; the multimode and PTV inlets add programmed temperature for trace work and thermally fragile compounds; cool on-column places the sample directly on the column for the heaviest analytes.

Column oven

Programs from 4 to 450°C across 20 ramps and 21 plateaus, with fast ramping to 75°C per minute on a 120 V oven and higher on 240 V.

Transfer line and ion source

Carries the separated compounds into the 5973N at controlled temperature. An independently heated electron-ionization source ionizes each compound, with optional chemical ionization on turbo-pump models.

Mass analyzer

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