8270 Sorbent Disk
$362.79
CDS Empore™ 8270 Extraction Disk — validated for U.S. EPA Method 8270E semi-volatile organic compound (SVOC) analysis in aqueous samples, manufactured and sold direct by CDS Analytical since 2019, the official Empore™ brand owner. Particle-loaded PTFE membrane technology delivers fast flow rates, easy reverse elution, and shorter drying times compared with traditional cartridge SPE.
Compliant with EPA methods:
EPA Method 8270E (using SPE per companion Method 3535)
Best for:
Quantitative extraction of 125+ neutral, acidic, and basic SVOCs from water
Wastewater, drinking water, groundwater, and leachate analysis
Compound classes including PAHs, phthalate esters, organophosphate esters, nitrosamines, chlorinated hydrocarbons, pesticides, haloethers, anilines, pyridines, quinolines, nitroaromatics, and phenols
Laboratories needing EPA-compliant SVOC workflows with reduced solvent consumption
Validated performance: Most of 125 tested SVOCs achieved recovery >75% with RSD <15% (250 mL water, 20 ppb, n=3). Read the full application note →

Recommended Workflow
For optimal recovery across the full SVOC range, the 8270 Disk is used as a composite disk stack with two Empore™ Activated Carbon Disks:
8270 Disk on top — retains target SVOCs
2× Activated Carbon Disks below — captures polar and reactive compounds
After loading the acidified water sample, the stack is dried, inverted, and reverse-eluted with DCM/methanol (acidic/neutral fraction) followed by DCM/methanolic ammonia (basic fraction).
