7697A Headspace Sampler, 12 Vial Capacity by Agilent Technologies

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 Automatic Liquid Sampler line of products.

Automatic Leak Check 

Ensure each vial is leak free prior to analysis, no loss of precision or sensitivity

Alternate Carrier Gas Options 

Safely work with hydrogen as a carrier gas to save laboratory cost

Priority Sample Positions 

Add late arriving important samples to the sequence without stopping and restarting

Barometric Pressure Compensation 

Provides increased precision regardless of laboratory pressure changes; consistent results from day to day and across multiple labs

Features:

• The 7697A Headspace Sampler 12 Vial Capacity configuration is perfect 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
• Software control through Agilent OpenLAB CDS software and Agilent MassHunter software
• Software control with Waters Empower™ 2 software and Waters Empower™ 3 software
• 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 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 depressurize before returning to tray
