Application Specific GC Columns. 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. By resolving PAH isomers, it provides easy, fast, and accurate quantification of PAHs in environmental and food samples. Select PAH provides full separations of EPA PAHs in less than seven minutes and EU PAHs in less than thirty minutes, including separation of chrysene, triphenylene, and benzofluoranthene (type b, j, and k), with no need for additional analysis.
CP-Sil 8 CB is a general-purpose phase that incorporates 5% phenyl groups in the dimethylpolysiloxane polymer, giving it slightly higher polarity than CP-Sil 5 CB. This delivers better selectivity for aromatic compounds and makes it the best choice for method development. Equivalent to USP G27 and G36, it shows excellent column-to-column reproducibility and very high column efficiencies. UltiMetal columns are recommended for the highest operating temperatures, and when working in rugged environments with process or portable instruments.
Application Specific GC Columns. CP-Sil 5 CB for Formaldehyde is optimized for the analysis of formaldehyde, water, and methanol in petroleum and petrochemical applications, and can deliver trace analysis of sulfur compounds and partial permanent gases (especially in switching systems). This nonpolar 100% dimethylpolysiloxane phase provides accurate separations based on volatility.
