Agilent 7697A Headspace Sampler, Agilent Technologies (CAT#: STEM-CPO-0253-ZJF)

The manufacturer of the Agilent 7697A Headspace Sampler, Agilent Technologies is Agilent Technologies.
Refurbished Agilent 7697A headspace autosampler (p/n G4557-64000).
Based on Agilent's automatic liquid sampler (ALS) technology, the 7697A Headspace Sampler features superior performance without loss or degradation of volatile components found in the gas portion of partitioned GC samples.
Headspace sampling allows the introduction of volatile compounds, from virtually any matrix, directly into a GC or GC/MS instrument. The technique is relatively simple when compared to other injection techniques, such as purge and trap, and keeps instruments cleaner than the standard liquid injection.

Condition: Refurbished, Certified Pre-owned
Valid Setpoints:
Oven Off, 35 °C to 210 °C
Valve and Loop Off, 35 °C to 210 °C
Transfer Line Off, 35 °C to 250 °C
Thermal Control:
All temperature zones (oven, valve and loop, transfer line) have setpoint increments in 1 °C with 0.1 °C resolution for actual temperatures and can be set to off

The 7697A Headspace Sampler 12-vial capacity configuration is perfect for academic labs and those with small sample loads
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
Control through Agilent OpenLab CDS software and Agilent MassHunter software
Other software control with Waters Empower™ 2 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 the tray
Transfer line interface accessory allows a headspace sampler and ALS to connect to the same inlet on the GC
