ABB Files Patent for Modular Gas Chromatography Device, System, and Method

ABB Ltd., Switzerland, has filed a patent titled “Gas Chromatography Device, System, and Method with Modular Architecture” with the China National Intellectual Property Administration (CNIPA), under publication number CN121678857A, filed in September 2025.

The patent describes a modular gas chromatography (GC) system designed to efficiently measure the properties of fluid samples while facilitating controlled discharge. The device features:

• A fluid inlet to receive samples and deliver them to a manifold plate.

• The manifold plate includes inlet and outlet channels, directing samples to an analysis module and discharging them after measurement.

• An analysis module, fixed to the manifold plate, houses a GC oven and sensor. The oven processes the sample from the inlet channel, while the sensor measures sample properties before the fluid is discharged via the outlet channel.

This modular approach allows for flexible system configuration, precise measurement, and streamlined sample handling, highlighting ABB’s continued innovation in industrial analytics and instrumentation.
