Varian Select™ pAh
Interference-free, Single-shot Solution for PAH Analysis
Please visit page 147 for full range of Varian Select Columns • No time wasted on false positives • Fast results with no need for further analysis • Low bleed reduces maintenance time and enhances sensitivity Varian Select PAH is the first capillary column that provides a single solution for PAH analysis by separating all the isomers, thereby avoiding false positives and inaccurate results. It provides easy, fast, and accurate quantification of PAHs in environmental and food samples by resolving PAH isomers. Varian Select PAH provides full separations of EPA PAHs in less than 7 minutes and EU PAHs in less than 30 minutes, including separation of chrysene, triphenylene, and benzofluoranthene (type b, j and k), with no need for additional analysis. Its one-shot technology saves money on capital investment and cost per analysis, and increases productivity. In addition, the low column bleed of Select PAH reduces the requirement for MS maintenance and enhances sensitivity.
