Agilent 7890B GC & NEW HTA HT2800T All-In-One Sampler

What you are buying

Most petrochemical, environmental, and food-safety methods call for the capillary GC separations the Agilent 7890B runs. This system pairs the 7890B with a new HTA HT2800T all-in-one autosampler, covering liquid, static headspace, and SPME sampling from a single rotating tower. Electronic pneumatic control meters the carrier gas to 0.001 psi; the heated inlet vaporizes the sample and carries it onto the column; the oven programs from 4 to 450°C; the detector measures each compound as it elutes. GenTech rebuilds, plumbs, and tests the inlets, detectors, and flow path, then verifies the complete system with the sampler installed.

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 HT2800T, made by HTA, combines liquid, static headspace, and SPME sampling in one rotating-tower unit, so the system needs only one autosampler instead of a separate unit for each technique. The rotating tower leaves the injector port clear for inlet maintenance. The sample rack sits away from the GC oven, which keeps samples from degrading or condensing at oven temperature. The robotic vial-handling mechanism moves each sample through the process in a fixed, repeatable sequence.

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. The 7890B holds up to two inlets.

All-in-one autosampler

The HT2800T handles liquid injection, static headspace, and SPME sampling from a single rotating tower, keeping the injector port clear for maintenance and the sample rack away from oven heat.

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.

Electronic pneumatic control

Meters carrier and detector gases to 0.001 psi and 0.05 mL/min, compensating for changes in ambient pressure and temperature.

Detectors

The 7890B carries up to three detectors matched to the chemistry: FID for hydrocarbons and general organics, TCD for fixed gases, micro-ECD for halogens and pesticides, NPD for nitrogen and phosphorus, and FPD for sulfur and phosphorus.
