Manipulating flow within

Agilent Technologies has introduced the 7890A gas chromatograph (GC) platform, delivering new levels of productivity, performance and flexibility.

Unique in-oven capillary flow technology opens up a suite of highly useful applications and enables productivity gains without the need to change existing methods.

Agilent engineers have achieved the goal of connecting, switching, splitting and diverting capillary gas flows inside the GC oven while keeping the hardware leak-free despite oven-temperature cycling.

The credit-card-sized component's small mass lets it closely track oven temperature for excellent analytical performance, and the design features low dead volume.

Connectors are equally rugged thanks to a new ferrule design that also minimizes tailing. Channels and connectors feature highly inert flowpaths.

The Agilent 7890A saves time before and after the chromatographic run, which means that users need not change their current method for the chromatographic run. This allows them to avoid extensive method development and revalidation. Agilent has also introduced a variable speed fan for faster oven cool-down.

On instruments equipped with the Agilent 7683 Automatic Liquid Sampler, sample injection preparation overlaps part of the oven cool-down ramp, further boosting throughput. When combined with the new, robust backflush capability, injection-to-injection time can be significantly reduced.

The Agilent 7890A features a fifth-generation electronic pneumatics control (EPC) and digital electronics that set a new benchmark for pressure regulation to 0.001 psi. This provides greater retention-time locking precision and contributes to the platform's superior reliability.
