Dr. Jaanus Liigand, co-founder and CEO of Quantem Analytics, will give a talk titled “Make your MS Analysis Quantitative Without Analytical Standards” and discuss with the membership their challenges, needs, and expectations for quantitative non-targeted analysis.
This meeting will occur on Tuesday, April 15th, from 12 pm – 1 pm EST.
Abstract: Quantification in non-targeted analysis remains a significant challenge due to the absence of analytical standards. Conventional approaches—such as the use of structural analogues or surrogate standards—often lead to high uncertainty. This seminar introduces Quantem, a machine learning-based solution that predicts ionization efficiency directly from molecular structure and analysis conditions. The method enables more reliable semi-quantification in suspect and non-targeted screening workflows, supporting better decision-making such as toxicity assessment or prioritizing which samples or compounds should undergo targeted analysis.
Comparative insights with traditional methods will be provided to highlight improvements in accuracy and applicability. Real-life case studies will demonstrate how predictive models can be effectively integrated into non-targeted analytical workflows.
