Significance of the topic

The 2024 Eastern Analytical Symposium & Exposition (EAS) is a major regional meeting that collects academic, industrial, and regulatory analytical scientists to address current challenges across the analytical chemistry spectrum. The program emphasizes cross‑disciplinary problem solving—combining separation science, spectroscopy, mass spectrometry, NMR, data science, and instrumentation—to support regulatory compliance, pharmaceutical development, environmental monitoring (including PFAS), forensic investigations, and emerging modalities such as oligonucleotide therapeutics. The meeting’s format (short courses, focused “conferences‑in‑miniature,” technical sessions, demos, and an exposition) supports skills development, technology transfer, and community building for both early‑career and experienced practitioners.

Objectives and overview of the program

This EAS edition aimed to: provide practical training (full‑day short courses); disseminate new science and applied methods (technical talks and e‑posters); showcase instrumentation and workflows (exposition and demo rooms); address regulatory and lifecycle topics (ICH Q14, USP expectations, nitrosamines); and highlight cross‑cutting trends (automation, AI/ML, sustainability, PAT). The conference theme Partners in Problem Solving framed sessions spanning environmental & food analysis, pharmaceutical analysis, mass spectrometry, separations, spectroscopy, biopharma/bioanalysis, forensic science, and data science.

Methodology and program structure

The meeting delivered content through multiple complementary formats:

• Short courses (full‑day) teaching fundamentals and advanced methods (e.g., HPLC/UHPLC, SFC, LC‑MS/MS method development, NMR, IR/Raman interpretation, PFAS, HPTLC).
• Thematic technical sessions grouping applied talks and case studies (e.g., PFAS analysis, nitrosamine control, oligonucleotide analytics, high‑throughput MS, spectroscopy at interfaces).
• E‑poster sessions for early career and student research dissemination.
• Hands‑on demonstrations and vendor demo rooms (notably Waters and Lazar Scientific) to illustrate instrument workflows and troubleshooting.
• Career and professional development activities (workshops, employment bureau, speed mentoring).

These formats enable side‑by‑side comparisons of analytical strategies (e.g., chromatographic modes, ionization/detection approaches) and expose attendees to complete analytical workflows from sample prep to data analysis and regulatory interpretation.
