AN1025: Simultaneous Extraction of PAHs and PCBs from Environmental Samples Using Accelerated Solvent Extraction

Instrument Type: Automated Sample Prep

Accelerated solvent extraction is an established technique to efficiently extract contaminants in solid and semisolid sample matrices with less solvent and time. Polyaromatic Hydrocarbons (PAHs) and Polychlorinated Biphenyls (PCBs) are considered toxic and carcinogenic, and therefore classified as persistent organic pollutants (POPs). Typically, PAHs and PCBs are extracted separately, using different solvent combinations. Our study demonstrates extraction of PAHs and PCBs using a single method from spiked mussel and from a soil spiked with a standard reference materials (SRMs).

Comparison of the retention for cytosine and naphthalene on a Thermo Scientific Acclaim Mixed-Mode HILIC-1 Column in reversed-phase and HILIC modes

Instrument Type: HPLC

The Thermo Scientific Acclaim Mixed-Mode HILIC-1 column is used for the analysis of cytosine and naphthalene in both reversed-phase and HILIC mode, and the retention compared.

Improved analysis of polycyclic aromatic hydrocarbons (PAHs) using a Thermo Scientific Hypersil GOLD HPLC column

Instrument Type: HPLC

The Thermo Scientific HPLC system is applied for the analysis of polycyclic aromatic hydrocarbons (PAHs). The separation is performed on a Thermo Scientific Hypersil GOLD HPLC column, with UV detection at 269 nm.
