The iGC-SEA Nova is based on Inverse Gas Chromatography (iGC) methodology, a gas phase technique for characterizing surface and bulk properties of solid materials. The principles of iGC are simple, with a uniformly packed cylindrical column with the solid material being analyzed. Pulses of contact concentration of gas are then injected down the column at a fixed carrier gas flow rate. The injected gas molecules passing over the material are adsorbed on the surface with a partition coefficient Ks:

Ks = Vn / Ws

Where Vn is the net retention volume – the volume of carrier gas required to elute the injection through the column, and Ws is the mass of the sample. With the Vn indicating how strongly the probe gas interacts with the solid sample, a wide range of surface and bulk properties can be calculated.

Advanced high-temperature capabilities

With a range of 10°C to 500°C, the iGC-SEA Nova’s high-temperature column oven enables in-situ sample preparation, surface energy analysis, and determination of diffusion coefficients, like carbon, at application temperatures.

Rapid surface characterization of highly active substrates

Efficiently characterize highly active substrates with rapid surface analysis capabilities, facilitated by the iGC-SEA Nova.

Unrivalled accuracy and reliability

The use of the iGC principle and innovative instrument features enable incredible accuracy and reproducibility in your results.

Fully automated operation

The innovative engineering of the iGC-SEA Nova, along with purpose-built control software, reduces operator time with fully automated experiments.

Versatility with up to 12 probe gas molecules

Leveraging up to 12 distinct gas probe molecules, conduct a diverse array of experiments, facilitating a broad spectrum of iGC measurements.

In-situ sample pre-conditioning

With modular accessories to enable in-situ sample preconditioning, understand how the surface properties of solids change at a range of temperatures and conditions.
