July Meeting: Dr. Sarah Choyke

Dr. Sarah Choyke (pronounced: Choy-key) will be speaking on the development of NTA products in a contract research environment. She is the Technical Director at Eurofins Environment Testing in Arvada, Colorado. She brings over 10 years of experience in analyzing emerging contaminants in the environment with expertise in field sampling, sample preparation, and mass spectrometry. She received her Ph.D from Duke University and her B.S. in Chemistry from Haverford College.

This meeting will occur on Tuesday, July 16th, from 12 pm – 1 pm EST.

Title: Knowing Known Unknowns: A Vision for Non-Targeted Analysis Product Offerings

Abstract: Current analytical methodologies typically quantify a predefined list of analytes using targeted methods. However, environmental field samples may contain additional analytes beyond this predefined list. Advances in high-resolution mass spectrometry (HRMS) have significantly enhanced the analysis of contaminants of emerging concern (CECs) through non-targeted analysis (NTA). For a commercial or contract laboratory, there is a heightened emphasis on meeting client objectives, turn-around-times, ensuring data quality metrics and adhering to specific report formatting requirements. To streamline these processes, we have adopted the Study Reporting Tool (SRT) framework as a template for clients to structure their projects and understand the workflow. The NTA workflow and report is designed to be adaptable to project-specific requirements, understandable to the clients, all while remaining manageable for laboratory staff. Due to the complex nature of NTA datasets, client input can drive the NTA to ensure data packages encompass pertinent data objectives while remaining comprehensible to all parties.
