HP 5890 Series II Plus GC with HT2100H Sampler

What you are buying

Many established petrochemical, environmental, and clinical methods still run on the capillary GC the Agilent 5890 delivers. The heated inlet vaporizes the sample and carries it onto the column; the programmable oven separates the mixture by volatility and affinity; the detector measures each compound as it elutes. GenTech rebuilds, plumbs, and tests the inlets, detectors, and flow path, then verifies the instrument against reference standards. You receive a 5890 that arrives verified and ready to run your methods.

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

Hewlett-Packard released the original 5890 in 1984 and followed it with the 5890 Series II, which added electronic pressure control. Both models run ambient to 450°C, with split/splitless, on-column, and PTV inlet options and single or dual detector slots for FID, TCD, ECD, and NPD. Electronic pressure control on the Series II gives more accurate, more reproducible flow and pressure than the original’s manual pneumatics. Agilent later inherited the platform from HP and phased out active support in favor of the 6890 and newer GC lines.

What each component does

Inlet

Vaporizes the sample and delivers it to the column. Split/splitless covers routine and dilute samples; packed and purged-packed inlets handle the older packed-column methods the 5890 still serves.

Column oven

Programs through a multi-ramp temperature sequence that separates the mixture by volatility. Reproducible oven control holds retention times steady across runs.

Pneumatic control

Manual or electronic pneumatic control meters the carrier and detector gases. Electronic control, on the units that carry it, tightens retention-time repeatability.

Detectors

The 5890 carries FID for organics, TCD for fixed gases, micro-ECD for halogens, NPD for nitrogen and phosphorus, and FPD for sulfur and phosphorus, up to two at once.

Labs that run this system

The 5890 Series II is method-compatible across the techniques most regulated and research labs run every day. These are the application areas buyers ask about most.
