2nd HPTLC Online User Meeting, hosted by the HPTLC Association
Promoting the use of HPTLC in plant analysis and other analytical fields is the main purpose of the International Association for the Advancement of High-Performance Thin-Layer Chromatography (HPTLC Association). For this, we bring together representatives from academia, industry, research, regulatory, and standard setting bodies.The “HPTLC Online User Meetings” shall facilitate a worldwide exchange of knowledge between HPTLC users and share the spirit of working in an exciting analytical field!
Using just classical Silica gel 60? There is more!
The stationary phase most commonly used in basic and High-Performance Thin-Layer Chromatography is the classic Silica gel 60 layer. It is also referred to as the normal phase. However, for many applications the choice of a modified silica gel layer could lead to a much better chromatographic result. Plus, the corresponding mobile phase may permit the use of less hazardous solvents. This session will discuss the diverse properties of available stationary phases, and present unique application examples to illustrate the possible improvements of separation conditions.
How to assess the safety of food products in absence of toxicological data
Assessing the safety of food is challenging as foods are complex mixtures containing thousands of known and unknown substances occurring at various concentrations. What is the best method to detect chemicals of most concern on which further toxicological investigations should be focused? Recent progress using Thin-Layer Chromatography (HPTLC) coupled to bioassays has been proposed as a breakthrough solution to fill some of the gaps identified with standard bioassays. In this session, HPTLC effect-direct analysis (EDA) for toxicologically relevant endpoints will be presented, anchoring bioassays and chemical analysis in complex mixtures of unknown composition with the goal to optimize and speed up decision-making in Food Safety.
Space for discussions – Meet the speakers and representatives from the HPTLC Association in a follow-up meeting held via Zoom at 15:15 BST
Take the opportunity to engage in discussions with speakers, colleagues, and representatives from the HPTLC Association in a moderated Zoom meeting, scheduled immediately after the main event. A separate registration for the Zoom meeting is not required – registrants for the main event will receive an email invitation with an access link one day prior to the event. Additionally, a QR code and a shortlink will be displayed after the Q/A session to bridge the gap, enabling a seamless transition from the webinar platform to the Zoom meeting also for last minute registrants.

Presenter: Maricel Marin-Kuan, PhD (Senior in vitro toxicology specialist, Nestlé Research)
Maricel Marin-Kuan obtained a Bachelor of Science in biological sciences with emphasis in genetics from the University del Valle in Colombia and a Ph.D. Degree in molecular biology at the University of Lausanne in Switzerland. Over 20 years’ experience in in vitro toxicology at Nestlé Research in Switzerland.Her experience includes the contribution to the improvement of the safety and quality through development and deployment of new in vitro toxicology approaches to assess safety of food - related ingredients and food contact materials(FCM).This has been critical as benefit for prioritization and decision - making in the field.Project manager involved in external industry and academy collaborations and supervisor of Master students.Responsible of the implementation of the High - Performance Thin - Layer Chromatography(HPTLC) facility at Nestlé Research in Switzerland in the Biodetection group.The main research application of HPTLC is devoted to the coupling of bioassays(e.g.endocrine activity and genotoxicity) to characterize complex mixtures in absence of toxicological data.
