HP 5890, sold as refurbished

The HP 5890 Gas Chromatograph

Scientific Equipment Source carries the Hewlett Packard 5890A and 5890 series II gas chromatographs. The 5890 series GC is one of the most widely used and reliable GC’s still in today’s laboratory. From the basic system with manual pneumatics and manual injection to electronic pressure control pneumatics and automatic sampling systems this GC can be fully customized to your application. They are many options to make this the exact system you need.

We stock all the options and accessories to get your system ready fast.We also service your existing GC’s and we carry a hugh stock of parts to do this.The 5890 is an excellent gas chromatograph at a lower price than the 6890. This gives you great performance on a smaller budget.

Some of the main features the system may include are:

  • Digital display of set points and actuals
  • Can be compatible with chemstation
  • 5 heated zones
  • Time table operation
  • Built in stop watch
  • Diagnostic function
  • Store and recall set points
  • 4 external event controls
  • Analog output
  • Electronic pressure control option
  • 3 ramp oven programming
  • Power failure recovery

Detectors

There are many detectors which can be used in gas chromatography. Different detectors will give different types of selectivity. A non-selective detector responds to all compounds except the carrier gas, a selective detector responds to a range of compounds with a common physical or chemical property and a specific detector responds to a single chemical compound. Detectors can also be grouped into concentration dependant detectors and mass flow dependant detectors. The signal from a concentration dependant detector is related to the concentration of solute in the detector, and does not usually destroy the sample Dilution of with make-up gas will lower the detectors response. Mass flow dependant detectors usually destroy the sample, and the signal is related to the rate at which solute molecules enter the detector. The response of a mass flow dependant detector is unaffected by make-up gas. Have a look at this tabular summary of common GC detectors:

 

Detector Type Support gases Selectivity
Flame ionization (FID) Mass flow Hydrogen and air Most organic cpds.
Thermal conductivity (TCD) Concentration Reference Universal
Electron capture (ECD) Concentration Make-up Halides, nitrates, nitriles, peroxides, anhydrides, organometallics
Nitrogen-phosphorus Mass flow Hydrogen and air Nitrogen, phosphorus
Flame photometric (FPD) Mass flow Hydrogen and air possibly oxygen Sulphur, phosphorus, tin, boron, arsenic, germanium, selenium, chromium
Photo-ionization (PID) Concentration Make-up Aliphatics, aromatics, ketones, esters, aldehydes, amines, heterocyclics, organosulphurs, some organometallics
Hall electrolytic conductivity Mass flow Hydrogen, oxygen Halide, nitrogen, nitrosamine, sulphur
