Original Press Release:



Our New Standard is the First to Contain all Major PAH Interferences



The new PAH interferences standard from Restek is the first and only certified reference material formulated to contain all major PAH interferences for priority PAHs. Analysts can use this mixture to quickly confirm the presence of common interferences by retention time comparisons.



PAH Interferences Standard (5 components)



The only standard formulated to contain all major PAH interferences for priority PAHs.



Pair with an Rxi®-PAH column and Restek’s EU 15+1 PAH standard to optimize method conditions and ensure separation of interferences and target PAHs.



Confirm the presence of common interferences by retention time comparisons.



Certified reference material (CRM) meets strict ISO quality requirements, making it suitable for quantitative use as a calibration or fortification standard.



PAH components are present in different concentrations so isomers can be distinguished by the difference in response factors.



Low-volatility toluene solvent provides longer shelf life, which helps ensure more accurate results.



Broad solvent miscibility—compatible with acetonitrile, the QuEChERS solvent.



HPLC compatible when diluted in appropriate solvent and analyzed with Pinnacle® II PAH columns or UHPLC compatible on the Pinnacle® DB PAH column.
