From Peaks to Insights: Navigating Environmental Analysis with Weck Laboratories using GC/MS/MS Instrumentation

This presentation highlights how Weck Laboratories leverages the latest triple quadrupole GC/MS (GC/TQ) technology—equipped with the advanced HES 2.0 (High Efficiency Source 2.0)—to deliver high-sensitivity, high-throughput analysis of complex environmental samples. We will demonstrate the performance of this system when applying EPA methods 8270 and 625.1 to real-world soil and water matrices.
As a full-service environmental laboratory operating at production scale, Weck Laboratories requires both sensitivity and reliability to meet tight turnaround times and maintain productivity. The GC/TQ system with HES 2.0 enables precise quantification of trace-level contaminants while requiring less sample volume. This reduces shipping and prep costs and minimizes instrument wear. The HES 2.0 source further enhances performance by increasing ion transmission, lowering detection limits, and supporting longer maintenance intervals—even when running challenging, matrix-heavy samples.
Attendees will see how this robust configuration improves data quality and throughput, particularly in routine environmental workflows. We'll explore how the system maintains stability over large sample batches and complex matrices without signal drift or fouling, ensuring uninterrupted analysis.
Ultimately, this session will demonstrate how integrating GC/TQ with HES 2.0 supports the demands of modern environmental testing—delivering reliable results with greater speed and efficiency.
