Choosing between solid-phase extraction (SPE) and direct injection can significantly impact your lab’s sensitivity, throughput, and sample integrity. In this session, Waters and PromoChrom experts explore the trade-offs between both approaches—from human involvement to analytical performance—while offering practical guidance for analyzing ultra-short chain PFAS. Whether you're optimizing for cost, compliance, or detection limits, this episode will help you make informed, workflow-smart decisions.
