Agilent 7890A GC System With 7697A Headspace Sampler

The Agilent 7890A GC with 7697A Headspace Sampler is a gas chromatography (GC) system with enhanced speed and accuracy for exceptional performance in the separation, identification, and quantification of complex mixtures.

This system includes a computer preloaded with Chemstation software, monitor, keyboard, mouse, and cables.

Agilent 7890A GC System Features:

• Advanced automation features and fast GC oven ramps at the lowest possible cost per sample
• Highly flexible EPC design enables even more sophisticated hydrocarbon analyses
• Capillary Flow Technology to enable flow modulation without the need for cryogen.
• Low Thermal Mass (LTM) system for direct, rapid heating and cooling ensuring faster GC analyses and higher sample throughput 
• Retention Time Locking (RTL) software to reproduce exactly the same results on multiple Agilent GC systems— configuration to configuration, location to location, operator to operator
  Robust backflush capability

The 7697A Headspace Sampler offers a 12-vial capacity configuration, making it perfect for academic labs and those with small sample loads.

7697A Headspace Sampler Features: 

• Standard 111 sample configuration with three priority samples
• Trays can be exchanged 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 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 the tray
