Overview of 7697A Headspace Control Software

The Agilent 7697A Headspace Control Software provides data system control of the Agilent 7697A headspace sampler (HS). After installing of the software, the HS becomes integrated into the Agilent data system as a part of the GC system. Access HS method parameters as you would access any GC sampler parameters, directly select the HS as an injection source, and create sequences that include headspace sample vials. The 7697A HS integrates more completely into the data system than any previous Agilent headspace sampler model.

Initial setup

Before using the 7697A Headspace Control Software for the first time, set it up as described in To Connect to the Headspace Sampler. You must provide the connection information (IP address or host name).

HS configuration

After first connection, configure the HS.

HS methods

Create and edit HS methods as part of the GC system. Wizards provide the ability to quickly:

• Create a new method based on a specific application.
• Convert existing G1888, 7694E, and other valve and loop HS methods.
• Convert existing pressure transfer HS methods.

HS online status

The Control Software provides online actual and vial status details, as well as a sampling diagram (depending on the data system).

HS sequences

Use the data system sequences to process samples and perform series of injections. The HS automatically optimizes vial processing to increase throughput. Simply select the HS as the injection source, then create the list of sample vial in the sequence.

What's new for users of previous Agilent HS models?

The 7697A HS integrates more completely into the data system than any previous Agilent headspace sampler model.

• No limitations on the number of methods in a sequence
• No limits on the order of samples in a sequence
• Directly select the sampler as an injection source
• Intersperse HS vials with other injections sources as desired (requires appropriate hardware, such as an automatic liquid sampler and optional G3520A 7890 transfer line interface accessory)
• Detailed status information, vial status information, and sampling diagram (availability depends on the data system)
• Normal data system sequence controls apply
