Agilent 6890 Gas ChromatographyImage Coming Soon

Agilent 6890 Gas Chromatography

Cambridge ID #: 15391

The Agilent/HP 6890N GC features electronic pneumatic control of all gas pressures and flows. On-board sensors automatically compensate for ambient temperature changes and barometric pressure differences to routinely achieve more accurate and reproducible results. EPC reduces re-calibration frequency and improves laboratory productivity. Designed to work seamlessly with the 6890N, the included 7683 Autosampler connects without a controller box or multiple power cords/outlets, and is packed with features including Agilent’s fast-injection technology.

 

Includes:

  • FID Detectors (Flame Ionization Detectors) OPtional
  • 7683 Autosampler (100 Vial Capacity)
  • Computer Loaded with Chemstation Software
  • Manuals and Cables

 

Features:

  • Electronic Pressure Control on detector and injector
  • Ambient temperature +4 °C to 450 °C
  • Temperature set point resolution: 1 °C
  • Supports 6 oven ramps with 7 plateaus, Negative ramps are allowed
  • Overview: Laboratories worldwide are looking for a GC solution that delivers reliability, performance, and reproducible results, And nothing produces these benefits like the Agilent 6890N Network GC. By integrating leading-edge technologies with an emphasis on quality manufacturing processes, the 6890N will bring a work ethic to your laboratory that’s matched only by your own.
  • Accomplish more with networking abilities
    • Lets you share business and scientific data easily within a laboratory and across sites for fast and informed decision making.
    • Incorporates local area network (LAN) technology as a standard feature, which makes it easy to link communication and control of multiple analytical instruments. With networking, you can work smarter, faster, and more economically.
  • Increased Laboratory Efficiency: Clock-time programming allows you to set up runs for unattended operation whenever you want. The system can be ready to work when you get to your laboratory. Pre-run and post-run commands automatically prepare the system for the next sample.
  • Decreased Calibration Time: You can manually enter existing calibration data and make a run with just one standard peak. The system can normalize the calibration table for you, allowing you to cut calibration time and avoid re-running your calibration standards.
  • High Sample Throughput: The 6890N network GC system is already set up for the Agilent 7683 automatic liquid sampler, enabling fast and easy installation. Single or dual injectors, equipped with either an 8-sample turret or a 100-vial sample tray, allow unattended operation. Using the 11-vial transfer turret with the tray and the solvent saving mode, you have enough solvent to run unattended eight times longer than before.
  • Minimal Rework: The Agilent 6890N network GC system is the only GC system that automatically selects the optimum pressure-control mode for split and splitless analyses. Forward-pressure control is best for splitless injections. Along with a large inlet liner volume and pressure-pulse operation, this mode reduces discrimination, sample degradation, and sample loss caused by liner overload while maximizing sensitivity. For split injections, the system automatically selects back-pressure control for linear split ratios over the entire usable split-ratio range and over wide column flow and pressure ranges. This reduces sample preparation and increases reproducibility and accuracy. Automatic switching between forward-and back-pressure modes yields optimal results in less time and with less effort.

Edwards E2M18 Vacuum Pump

Cambridge ID #: 661

This Edwards 18 E2M18 Two Stage Rotary Vane Pump is in excellent condition.  The EM range of oil-sealed rotary pumps - renowned for their high ultimate vacuum, rapid pumping speed, quiet operation and ability to handle vapour - have become the industry standard for laboratory and light industrial applications. The E1M18 and E2M18 pumps are direct drive, sliding vane pumps. The pump is oil sealed and designed for reliable, long-term operation. The pump is a freestanding unit with the drive provided through a flexible coupling by either a single-phase or three-phase (four-pole) motor. This is a single stage oil sealed rotary vane pump which has a pressurised oil system that lubricates the pump shaft bearing surfaces and rotor sealing faces. The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents oil suckback unless the gas ballast valve is open.
