23 – 27 May 2022


Online Festival

A week-long online celebration of Inverse Gas Chromatography

We invite you to join us for iGC-SEA Week, a week-long series of special releases and events curated to share the latest research, resources, and insights involving Inverse Gas Chromatography, and the iGC-SEA instrument.

Inverse Gas Chromatography is a powerful technique for materials characterization, providing unparalleled insight and accuracy in surface property analysis. As the inventor of the world’s first purpose-built (and still most advanced) instrument employing the technique, the iGC-SEA, Surface Measurement Systems have been pioneers of the technique for over two decades.

iGC-SEA Week, taking place 23 – 27 May 2022, is a free one-week event that will see new content, exciting online educational events, and great iGC resources released every day, giving you all the knowledge needed to maintain the highest standards of excellence in your work involving iGC.

WATCH: Dr. Anett Kondor discusses her history with iGC,
the benefits of the technique, and more…

Novel Research on Applications of Surface Energy Analysis

Speakers:
Prof. Daryl Williams, Dr. Daniel J. Burnett, Surface Measurement Systems


An in-depth online workshop featuring leading experts on iGC, exploring their recent research into applications of surface energy analysis.

This session will be delivered by two of Surface Measurement Systems leading scientific authorities, Prof. Daryl Williams and Dr. Daniel J. Burnett. Listeners will be able to hear their latest findings employing iGC in real-world research applications, and have an opportunity to engage them directly in a live Q&A.

Abstract:
Surface energy is an important parameter for the characterization of surface properties. It can provide a useful picture of the energetic situation on the surface and shows a strong dependency on various macroscopic material properties.  For example, it is directly related to the interfacial adhesion between two surfaces.  In particular to biomaterials understanding the surface interactions of these materials becomes important as these could influence their biological reactivity, binding or adsorption interactions in different bioprocesses as well as the functionality of several biomolecules.  In this review presentation, several case studies focused on measuring the surface energy and wettability of proteins, bioglasses, bone cements, and dental materials will be introduced.  Work will be highlighted by recent investigations from the authors.  In particular, the surface energy as a function of relative humidity was investigated on proteins and glycine oligomers.  In addition, previously published work from other groups will be introduced.

Abstract:

The surface characterization of pharmaceutical powders is critical for many of the unit processes which occur with the manufacture of particulate based solid state dosage forms. In particular the surface energy and the surface area are arguably the most important two surface property descriptors.  This presentation which illustrate how IGC can be used to measure the surface area of low surface areas pharmaceutical solids, including the surface area as a function of relative humidity. In the main part of this talk the wide range of unit processes will be highlighted where the importance of powder surface energy can be demonstrated including granulation, powder flow, powder milling and dissolution. In particular the usefulness of surface energy heterogeneity mapping using IGC will be highlighted.

Wednesday 25 May: iGC Scientific Bulletin

Every month, more and more case studies and articles are published with valuable insights provided using the Inverse Gas Chromatography method. We’ve gathered these together in a single useful collection to enable you to catch up on the last 6 months of published research, and keep a useful list of references for your future research.

New IGC Application Spaces for High Temperature Measurements

Speaker:
Dr. Anett Kondor, Surface Measurement Systems


Giving you your first look at a brand new iGC product from Surface Measurement Systems, leading global expert of iGC Dr. Anett Kondor will explore brand new applications employing a high temperature oven. This hugely exciting webinar will offer a unique look at what’s in store for the future of iGC-SEA.

Inverse Gas Chromatography (IGC) is a rapid technique to determine thermodynamic parameters of gas–solid interactions and to characterize physicochemical properties of solid substrates. IGC offers its applicability where it is difficult and even impossible to characterize the surface of some forms of solids (powders and particulates) by means of other popular techniques as wetting method or FTIR. Solids and highly viscous liquids in many forms can be easily studied by means of IGC [1]. In this short presentation we will show three applications of IGC at high temperature and I will introduce the new IGC- SEA system with high temperature oven.

First, adsorption isotherm data of several alkyl aromatic hydrocarbons (benzene, toluene, ethylbenzene, o-xylene, m-xylene and p-xylene) were measured in the temperature range of 423–523 K on a partially dealuminated faujasite type DAY F20 zeolite by inverse gas chromatography. The gas–solid equilibria and modelling were interpreted on the basis of the interfacial properties of the zeolite, by dispersive, specific and total surface energy heterogeneity profiles and distributions of the adsorbent measured by surface energy analysis.

Diffusion and mass transfer play a significant role in several materials processing operations. Diffusion and mass transfer are also of crucial importance in affecting the structure of solid products including segregation phenomena in castings and impurity distribution in crystal growth [2]. In the second study diffusion coefficients of cyclohexane and toluene on two catalyst samples measured at 523 °C and 573 K and the uncertainty in the measurement was also determined.

In the last study, we investigated the thermal stability of anode and cathode materials by measuring the surface energetics at different temperatures, which is important during development of the battery materials, besides energy density, power density, lifetime, charging rate, cost and safety.
