The iGC-SEA continues Surface Measurement Systems’ pioneering history with inverse gas chromatography (iGC), which now spans more than fifteen years.

The iGC-SEA is a second generation iGC instrument. It is the world’s only commercial instrument based on the iGC principle. The unique SMS injection scheme provides a wide range of injection concentrations with unrivalled accuracy and reproducibility.

How Does the iGC-SEA Work?

The iGC-SEA is based on Inverse Gas Chromatography (iGC) methodology and is a gas phase technique for characterising surface and bulk properties of solid materials. The principles of IGC are very simple, being the reverse of a conventional gas chromatographic (GC) experiment.A cylindrical column is uniformly packed with the solid material of interest, typically a powder, fibre or film. A pulse of constant concentration of gas is then injected down the column at a fixed carrier gas flow rate, and the time taken for the pulse or concentration front to elute down the column is measured by a detector. A series of iGC measurements with different gas phase probe molecules then allows access to a wide range of phyisco-chemical properties of the solid sample.

The injected gas molecules passing over the material adsorb 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. VN is a measure of how strongly the probe gas interacts with the solid sample and is the fundamental data obtained from an IGC experiment; from it a wide range of surface and bulk properties can be calculated.

Rigid cans and jars can also be tested using the simple-to-use can piercing station which supports the cans and jars for accurate analysis using a standard needle probe. A 45° Adaptor is also available to aid measurement of small volumes of headspace.

There are a variety of ways to perform analysis; Timed Tests, AutoSense, Peak/Valley, Syringe Direct Injection or Continuous Testing. Fast configuration and selection provides the test method which is best for you. Easy to see Pass and Fail messages speeds up the analysis process and removes any uncertainty with interpreting measurements.

The Gaspace Data Manager software allows you to download results stored on your gas analyzer and upload new settings. You can also search through your stored data by time, date, user, production line or any of the product information.

The TME BT Integra-Pack© is a bench-top, highresolution (0.001 psig) test instrument with a small footprint and user-friendly ease of operation. Electronic pressure and flow controls provide precise and repeatable test conditions, while automatic and high flow output allow testing of large porous packages. Applications cover a range of flexible or rigid, porous and non-porous, open or sealed packages.

Automatic or Manual Parameter Definition 

The intelligent BT Integra-Pack will test any package in automatic mode, with no need to input test parameters. However, its sophisticated nature is combined with a manual mode that lets the user input parameters such as ramp rate control and back pressure drop sensitivity. This allows testing of special configurations or types of packages or perform specific research and datagathering activities.

Icon-based, Touch-Driven Color Display

The touchscreen color display provides easy, clear navigation through the wide variety of data handling and review screens. Clearly defined icons make it easy to choose test modes, move from automatic to manual test settings, view test results in numeric and/or graphical format, and securely handle accumulated data.

Modular systems for precision water vapor permeabilty testing of packaging film barriers.

The Digital Ink Rub Tester uses the Sutherland-method and is designed to measure scuffing or ink rub resistance. Several tests can be performed including dry rub (the amount of transfer ink from one dry surface to another), wet rub (the amount of transfer of ink from wetted surface to another), wet bleed or transfer (ink transfer to a water-saturated blotter), wet smear (similar to wet bleed with the addition or rub cycles), functional rub/wet rub (smear or transfer tests using a liquid other than water and hot abrasion). An optional heated weight provides the 10-20 Rub Resistance Tester with a uniform test for evaluating hot abrasion resistance of printed materials like fabric, plastics.
