Breakthrough Capillary Flow Technology Reliably Manipulates Flow Inside Gc Oven, Enabling New Applications

Agilent Technologies Inc. has introduced the Agilent 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.

"Throughput is important to all GC users, and the Agilent 7890A delivers more analytical runs per day by a substantial margin," said Shanya Kane, Agilent vice president and general manager of GC Systems. "We looked at the entire platform in devising ways to reduce cycle time, and this holistic approach also helped us solve difficult applications challenges. Our main intent is to make the benefits of this technology accessible to the wide range of chromatographers."

Capillary Flow Technology: A Breakthrough in Solving Application Problems. Agilent engineers have achieved the long-sought-after 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.
