Video about optimizing your IGC measurements by Prof. Steven Abbott
After the series about IGC Steven Abbott added another video in which he explains how you can optimize your IGC measurements. You also find the text on his website
IGC explained by Prof. Steven AbbottAt the IGC Symposium in June 2016 Prof. Steven Abbott already presented his app for IGC. Now he produced a series of videos and explains the method and the details of IGC and the IGC measurements. Use this great opportunity and learn more about IGC at your desk. Start with the basics and then discover the details in these 4 videos (5 - 7 min each).

We would love to hear your comments or questions on this. Please share them in the comments below.  Panel with: Ralf Duempelmann, Eric Brendle, Adam Voelkel, Steven Abbott, Matthias Kellermeier It was already the 5th time that the IGC Symposium took place on 14th June 2016. This year the theme was:
Surface Analysis by Dynamic Adsorption Methods in Gas and Liquid Phase. We always try to have a mix of speakers from both industry and academia to showcase the use and benefits of IGC in the business and to hear new insights and developments from research at technical universities. The speakers and participants came from different countries, like UK, Germany, France, Switzerland, Poland and Czech Republic. The speakers presented very different aspects of IGC and ILC. For example Dr. Steven Abbott released the new online apps for IGC (more details will follow later) and I shared some critical assumptions in IGC measurements and their impact. The IGC symposium is the best place to learn more about IGC, if you are new to this method. Here you find all the IGC experts and you can talk to each of them in person. Diversity and longterm experience in IGC You can see the diversity and richness from the speakers and presentations:

This is our second christmas with Inolytix. And besides of the christmas cards we sent to special clients and partners, we wanted to do something different this year for all our contacts. That is why we created this short video and hope that it will give you 25 seconds to stop your work and relax a little bit and enjoy the christmas jingle. We wish you Merry Christmas and a Happy New Year 2016. Ralf Dümpelmann & Sabine Schmelzer  You haven't heard from me for a long time (busy, busy, busy!) but don't worry, the Inolytix adventure is still ongoing!
Time to grow A lot of new developments have been happening in the shadows and it's time to turn on the lights. Just like a seed taking root and slowly growing into a tree, customer relationships need time to develop and turn into fruitful enterprises. Unlike in the IT market where the number of clicks per day counts, or in the B2C market where the number of clients can quickly reach several thousands, the B2B market is all about relations, trust, and… relations! Two examples may illustrate this slow path to success. Strong development with IGC My first experience began some 2 years ago, when I contacted Eric Bendle from Adscientis. We agreed on a partnership 6 months after initial contact. His proposal to have me moderate his IGC Symposium in June 2014 took me by surprise, and one year later I organized the same Symposium for him*. During the 2014 event, we met a key individual and it took 8 months before we met again and today, we are proud to be their improvement team in charge of their internal IGC analytics. Another example underlying the critical importance of time: it took a third business partner and 12 months of patience to finally receive an order for the IGC software and hardware. It will be delivered very soon, so crazy! Microtomography - a new look into solid samples My second experience is pretty different but also took a significant amount of time. In 2014, I saw a presentation from a young Ph.D. student about image analysis and tomography. Although interesting, I was questioning myself about the relevance of the presentation. I sought him out several months later, we met, and I understood more the intricacies of the technique. In March 2015, I planned to attend a catalysts conference and I had the idea to promote his image analysis and microtomography. We made several iterations to condense 5 pages of scientific "promotional material" into a neat 1 page flyer. Today, our customers are able to see images never seen before, an exciting start for new product developments and greater insight into studied systems... Taking off... They say a startup needs 3 years to really take off. Being generally impatient myself, I was wondering why 3 long years? After almost 2 years of life, Inolytix is off to a nice start and still needs to invest time into developing lasting relationships to grow. After all, you can still be on the right path even if the success is not there right away. I'm pretty sure about that and have some confidence now... *N.B: the 5th IGC Symposium will take place in Munich, June 14th, 2016!

Use IGC to discover hair treatment and damages
Inverse Gas Chromatography (IGC) was the analytical tool of choice for surface characterizations of hair (and hair treatment), pigments (compatibility) and silica (for tyres). These were some of the interesting insights of the IGC Symposium, April 10th in Frankfurt organized by Adscientis and Inolytix, http://inverse-chromatography.com/.
Dr. von Vacano, BASF, showcased physical characterization studies of native, bleached and treated hair using AFM, XPS, ZP (surface charge) and IGC. The dispersive surface energy measured by IGC is the best indicator for surface damage with low statistical errors and the best quantification. Even the promotion of a new product uses the evidence by IGC. The combination of all methods provided a thorough understanding of hair damages and conditioning.
Measurements of pigment surfaces
Dr. Gebhardt, DSM Coating Resins, presented measurements of pigment surfaces by IGC and some surprising findings in term of acid/base character, nano-roughness and specific chemical interactions. The question behind this study was the compatibility to the resin matrix, the coating formulation and treatment of the pigments. The results, like basic properties and high affinities to nitrile, amide and carbamate groups, can be used to optimise pigment-coating systems. Pigment suppliers were encouraged to share information about surface treatment and potentially collaborate.
The next generation of energy saving tyres
Dr. L. Guy, Solvay, explained the challenges to develop next generation of energy saving tyres and the interactions between silica surface, carbon black and the polymer nature. The use of IGC is key to understand these interactions. Useful are the different techniques as IGC-ID (infinite dilution) to measure dispersive surface energy and IGC-FC (finite concentration) to measure the surface heterogeneity and e.g. BET with alkenes instead of N2.
Highly qualified experts delivering additional applications
Additional background information and further applications of IGC was provided by professors of different universities. The introduction was presented by Dr. H. Balard, who started using IGC in the year 1978 and published 52 articles on IGC.
Altogether, this was an inspiring symposium with highly qualified experts. There is no fancy new equipment behind IGC (which may explain the lack of broader interest…), but simply a really valuable methodology and expertise. Personally, I am certain that more and more R&D departments will take advantage of it – sooner or later.
