Webinar: Absolute Configurations of Complex Enantiomers by VCD on 9 September 2021
Very often, the absolute configuration of chiral centers of complex APIs, proteins or natural products is initially unknown and tricky to determine. Singly crystal X-ray crystallography is the method of choice, if single crystals are available and representative – but what, if not?
Vibrational Circular Dichroism (VCD) is based on IR spectra of left and right circularly light. Measurements can be performed in liquid, dissolved, gaseous or any solid form. Key is not only the measurement, but also the computed spectra of specific Absolute Configurations and the data comparisons. For molecules with multiple chiral centers, VCD is an absolute and independent technique that directly probes the chirality at multiple chiral centers in a single measurement. There are various stages at which VCD is best performed. One is for example in the beginning of a study of complex enantiomers to establish the right configurations and the respective references for chiral HPLC.

10th International IGC Symposium on 15 June 2021
The Art of Molecular Surface Sensing by Inverse Gas Chromatography
The 10th IGC symposium focuses on effective and valuable surface characterization of powders, fibers and plates based on the dynamic adsorption of up to 20 different gas probes, also known as Inverse Gas Chromatography (IGC).
The Art of Molecular Surface Sensing by Invers Gase Chromatography was chosen as this year’s caption to highlight the more subtle aspects of IGC, especially the use of different concentrations ranging from ideal single probe molecule adsorption to full surface coverage and adsorption isotherms.

Webinar: Cocrystals - the Champions League of
Solid-State Pharma Formulation
On 16 April 2021 we organized a webinar together with our partner Solidchem.
Dr. Carsten Schauerte, CEO, provided information about advantages of crystallization, but also the complexity and difficulties of cocrystal screening.
He presented a new method to improve the conventional screening approach by a goal-oriented way of using ternary phase diagrams prior to and in combination with the actual screening procedure.

Tipps & Tricks for IGC: From Sample Preparation to Successful Measurements
On the 10th February we held the second webinar about IGC with more than 60 registrations from Europe but also from India, China, Egypt and Canada which was a great surprise for us.
In this webinar we presented and explained step-by-step the sample preparation, choosing, how to fill column properly and how to run first experiments with alkanes and polar probes.

The 10th IGC Symposium was online on 16 June 2020
In the actual situation of Stay at Home we decided to turn the planned IGC symposium into an online and FREE event on 16 June 2020. The theme of this symposium was 'Review - Validate - Future':
Validation: for the first time 16 different labs from industry and academia participated in an IGC round-robin test. Results were presented and discussed – to check and validate IGC procedures.
Review: the commercial use of IGC is around 20 years old, e.g. Adscientis is celebrating its 20th anniversary in year 2020! What experiences have been made and which advances were made?
Future: During the last years new ways to use IGC and new applications have been explored. Some examples will be presented and new concepts were discussed.

The 8th International IGC Symposium on 4th June 2019 in Cologne
Effectiveness is Key in Industry
This year's symposium focused on effective and valuable surface characterization of powders and fibres and other materials based on the dynamic adsorption of up to 20 different gas probes, also known as Inverse Gas Chromatography (IGC).
Novel practices, good experiences and the exchange of all participants were the motivation of this symposium since its beginning. The symposium is the best place for
participants to understand the potential of surface characterization by molecular probes, the pitfalls of different practices and the practical use for the different applications in industry.
Good practices as well as critical aspects and supporting techniques were outlined. And structured discussions intensified the exchange of experiences – like in the successful 2018 symposium.

3rd European Chemistry Partnering on 26 February 2019, Frankfurt, Germany
Ralf Duempelmann pitched for the second time at the 2nd European Chemistry Partnering Event. Last year it was a great opportunity to present our analytical services and to connect with many different experts from the chemical industry.
This year ECP had 850 participants with a comparable industrial quota. The well organized 1:1 meetings were a great opportunity to connect with new potential customers and partners.

XIX Workshop at Porotec on 13 - 14 November 2018
At the Porotec Workshop Ralf Duempelmann presented for the third time results and best practices of IGC measurements and highlighted the new automated instrument for Inverse Gas Chromatography.
The 7th International IGC Symposium on 19th June 2018 in Cologne
This symposium showcased experts who all use dynamic sorption methods also known as inverse gas and liquid chromatography (IGC, ILC). In IGC the adsorption behavior of 15-25 different probe compounds is used like AFM tips to characterise the properties.
The program presented the latest, most up-to-date knowledge and experience on surface characterisation of powders and fibres. Good practices as well as critical aspects and supporting techniques were outlined (see abstracts). Structured discussions intensified the exchange of experiences – like in the successful 2017 symposium.
The one-day program was compact and ideally suited for industry representatives from R&D, product development and analytical departments as well as researchers from institutes.
