Environmental and Food Analysis: 201TP and202TP Specialty Reversed-Phase ColumnsPolyaromatic hydrocarbons (PAHs) are large organicmolecules produced during combustion. Many PAHsare carcinogenic. For this reason the United StatesEnvironmental Protection Agency (EPA) and othergovernmental agencies have formulated regulationsfor the monitoring and control of PAHs and havedeveloped methods for their measurement in air,water, food, and other components of the humanenvironment.The EPA has designated sixteen PAHs as PriorityPollutants (see Figure on page 54). EPA Methods 610and 550 deal with the measurement of PAHs indrinking water and Method 8310 deals with themeasurement of PAHs in waste water. These EPAmethods specify reverse phase High PerformanceLiquid Chromatography (HPLC) for measurement ofthe PAHs.Vydac 201TP HPLC columns have long been thestandard in the analysis of PAHs by HPLC. Vydac201TP and 202TP HPLC columns have been specificallydeveloped to perform the separation and quantitationof PAHs required by environmental regulations – notonly regulations presently in force but also newregulations on the horizon.Vydac 201TP columns have been used to establishstandard reference materials (Ref. 1, 5*), measure airquality (Ref. 1-4*), measure PAHs in sediments(Ref. 6*), quantitate PAHs in food (Ref. 7-8*), andstudy high molecular weight PAHs (Ref. 9*). Theyhave also been used in the study of shape selectivityof reversed phase materials.* References on page 56.Ordering InformationCat.No.Description201TP54 Specialty Reversed-Phase Column, C 18,5 µm, 300 Å, 4.6 mm i.d. x 250 mm201TP5415 Specialty Reversed-Phase Column, C 18,5 µm, 300 Å, 4.6 mm i.d. x 150 mm202TP54 High-Carbon-Load Reversed-Phase Column,C 18, 5 µm, 300 Å, 4.6 mm i.d. x 250 mm202TP5415 High-Carbon-Load Reversed-Phase Column,C 18, 5 µm, 300 Å, 4.6 mm i.d. x 150 mmRapid-Analysis Column:202TP3405 High-Carbon-Load Reversed-Phase Column,C 18, 3 µm, 300 Å, 4.6 mm i.d.
