Semivolatiles Columns<br />

Semivolatiles are usually extracted from soil samples or other environmental matrices. GC<br />

columns with precise retention time reproducibility and good mass spectrometer performance<br />

are key enablers for these often demanding analyses.<br />

Recommended Columns for Semivolatiles<br />

• HP-5ms, DB-5.625, DB-5ms Ultra Inert, HP-5ms Ultra Inert for EPA methods 8270 and 525<br />

• DB-XLB for PCB congeners<br />

• HP-5ms, DB-5ms Ultra Inert, HP-5ms Ultra Inert or DB-35ms for PAHs<br />

• DB-5ms, DB-5ms Ultra Inert or DB-XLB for phenols<br />

DB-Dioxin<br />

• Specifically engineered for the analysis of polychlorinated dibenzodioxins (PCDDs)<br />

and dibenzofurans (PCDFs)<br />

• Resolves 2,3,7,8-TCDD and 2,3,7,8-TCDF from all other isomers in one run<br />

• Low bleed<br />

• Bonded and cross-linked<br />

• Solvent rinsable<br />

Similar Phases: SP-2331, 007-23, Rtx-2332, CP-Sil 88, Rtx-Dioxin<br />

Note: 100 psi regulator required to reach optimum carrier gas velocity<br />
