Agilent 7697A
The Agilent 7697A Headspace Sampler, in both 111 and 12 vial capacity configurations, represents the state-of-the-art in headspace gas chromatography. It is based on the architecture of the market leading 7890 Series GC and 7693A ALS line of products.
Independent control of vial pressurization and column head pressure provides increased precision. Barometric pressure compensation ensures the increased precision is consistent from day to day and across multiple labs. Perform method conversion from any headspace method to 7697A without any rework.

- The 7697A Headspace Sampler 12 Vial Capacity configuration is meant for academic labs and those with small sample loads
- Standard 111 sample configuration with 3 priority samples
- Exchangeable trays during a sequence for increased sample capacity
- Hydrogen carrier and auto Sleep/Wake modes conserve valuable laboratory resources.
- Independent control of vial pressurization and column head pressure provides increased precision by ensuring no back pressure during sample transfer.
- Automatic vial leak test checks each vial during pressurization – without time consuming calibration - to ensure that every sample is properly capped.
- Sample Bar Code Reader with data transfer capabilities allows you to track samples before they enter the oven.
- Multiple headspace concentrations (MHC) with up to 100 extractions per GC start allows for a more complete sampling and increased sensitivity
- Multiple headspace extractions (MHE) with up to 100 extractions per vial
- Supports 10 mL, 20 mL, or 22 mL vials without an adapter
- Method development software transfers methods from any headspace system or quickly designs a method from scratch using just a few known parameters.
- Samples depressurized before returning to tray
