Agilent 7697A Headspace Sampler

What you are buying

A refurbished Agilent 7697A Headspace, a headspace sampler. It samples the vapor above the sample for volatile analysis; it runs unattended sequences.

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

Agilent built the 7697A on the same architecture as its 7890 GC and 7693A automatic liquid sampler. An inert sample pathway carries the vapor to the GC without analyte loss or degradation. An automatic leak check confirms each vial is sealed before the run starts. The sampler stores up to 32 user-defined headspace methods, plus five presets, and up to 9 sequences. An operator can run it standalone from a chemical-resistant keypad or over LAN through OpenLab CDS ChemStation, OpenLab CDS EZChrom, or MSD ChemStation. Independent control of vial pressurization and column head pressure keeps sample transfer free of backpressure. Priority sample positions accommodate a late-arriving sample without breaking the sequence. Barometric pressure compensation holds results consistent across instruments and labs. The 7697A runs on hydrogen as a carrier gas. Sleep and Wake modes cut gas and power use between runs.

What each component does

Vapor sampling

Samples the vapor above the sample for volatile analysis, without carrying the liquid or solid matrix into the GC.

Automated sequencing

Runs overnight sequences without an operator, working through the loaded tray on its own schedule.

Technical detail

*OEM specifications for brand new instrument.

Labs that run this system

The 7697A is method-compatible across the techniques most regulated and research labs run every day. These are the application areas buyers ask about most.
