Atlantic® & Pacific® Disk Selection Guide

Importance of SPE Disk Selection

Solid phase extraction (SPE) disks provide a robust platform for isolating and concentrating trace organic contaminants from environmental and industrial samples. They are critical for ensuring reproducible recoveries, compliance with regulatory protocols, and efficient use of solvents and time.

Objectives and Overview

This guide presents the Atlantic & Pacific SPE disks portfolio, detailing disk chemistries, part numbers, compatible methods (US EPA, ISO, EN), and selected application notes. It aims to streamline disk selection based on analyte classes (e.g., pesticides, PAHs, PCBs, PFAS) and sample matrices (drinking water, wastewater, seawater, sediments).

Methodology and Instrumentation

• Disk chemistries: C18, high-capacity C18, DVB-D, HLB (L, M, H), One Pass, hexane-extractable.
• Part numbers corresponding to 47 mm and 100 mm disks.
• Automated SPE systems: SPE-DEX 4790, 1000/3000XL controllers with Envision platform.
• Analytical detection: GC/MS, GC/MS/MS, LC-MS/MS for target compounds.
• Compliance: US EPA Methods (e.g., 506, 525.3, 1664A/B), ISO 9377-2, EN methods.

Main Results and Discussion

• C18 disks (47-2346-02) suit organochlorine pesticides, PCBs, PAHs, dioxins in wastewater per EPA 608 and SL-392-2007.
• High-capacity C18 disks enhance loading capacity for trace targets in drinking water.
• DVB-D disks enable extraction of nonylphenol, bisphenol A, explosives, hydrocarbons under EPA 525.3 and EN16691.
• HLB variants offer broad-spectrum retention for pharmaceuticals, personal care products, phthalates, PPCPs across diverse matrices and methods.
• One Pass disks facilitate multi-residue extraction of semi-volatiles in complex wastewater samples.
• Hexane-extractable disks conform to EPA 1664 for oil & grease analysis, reducing operator time via automated workflows.

Benefits and Practical Applications

• Enhanced reproducibility and method compliance across regulatory standards.
• Reduced solvent consumption and faster sample throughput through disk SPE.
• Versatility across multiple analyte classes and sample types including surface water, wastewater, and seawater.
• Automated integration improves laboratory efficiency and data quality.

Future Trends and Opportunities

Emerging needs include disks tailored for per- and polyfluoroalkyl substances (PFAS) and other new contaminants. Advances in polymeric phases and miniaturized formats will support high-throughput screening by LC-HRMS and in-field applications. Integration with digital sampling platforms and green solvents will further drive innovation.

Conclusion

The Atlantic & Pacific SPE disk portfolio offers a comprehensive selection for efficient, compliant extraction of a wide range of organic contaminants. Strategic disk selection optimizes recovery, throughput, and regulatory adherence, meeting the evolving demands of environmental and industrial analysis.
