PAH Internal Standards

PAH internal standards are polycyclic aromatic hydrocarbon mixes added to samples and calibrators before GC-MS or HPLC analysis. Environmental and food testing laboratories use them to correct for recovery losses and injection variability in PAH methods.

Currently the range holds a Reagecon Polycyclic Aromatic Hydrocarbon (PAH) Internal Standard, a six compound mix supplied in dichloromethane. It pairs with the PAH Standards listed under Organics, so a calibration series and its internal standard can be sourced together from the same supplier.

Choose an internal standard whose compounds are resolved from the target analytes in your chromatographic method, and confirm that dichloromethane suits your extraction and concentration workflow. Ask Lancetech Limited for a quotation if you need a different mix or solvent.
